In fig. 1A all the measuring units 2 are positioned at their upper most position and it can be seen in fig. 1A that in this position, the lower parts of each measuring units 2 are easy accessible as they are positioned in navel position of the operator. In fig. IB, all the measuring units 2 are positioned at their lower most position and in can be seen from fig. IB that in this position, the upper parts of each measuring units 2 are easy accessible as they are positioned in the navel position of the operator. It is noted that the measuring units can be positioned at any of such upper most or lower most positions.

To provide the positioning of the measuring units 2, the rack further comprising a mechanically activated position system to which the unit frame 3 of each of the at least one measuring unit 2 is connected. Thereby, as the measuring devices are connected to the unit frame 3, a movement of the unit frame 3 will effectuate a movement of measuring unit 2.

As disclosed above, the mechanically activated position system is configured to position each of the least one measuring unit 2 at different vertical positions in the rack frame 1.

Ventilation is preferably integrated locally in the rack frame and/or in the unit frames in order to limit exposure of hazardous or toxic fumes, vapours and exhaust air, to improve EHS (Environmental, Health and Safety) and to keep measuring units tempered. Ducts and wires and pipes are preferably flexible and capable to fit any measuring unit position when operated.

Preferably, the mechanically activated position system to which the unit frame 3 of each of the at least one measuring unit 2 is connected comprising a first rail system extending vertically in the rack frame 1. The first rail system may be provided in or on the back of the rack frame 2 and/or in or on the vertical side parts 1.1. In the embodiment shown in fig. 1A, this first rail system comprising rails 10 (not visible in fig. 1) on which carriers 16 are arranged. The carriers 16 may be connected to the unit frames 3 to the unit frames 3. In the embodiment shown in fig. 1A the carriers 16 are connected to the unit frames 3 through a beam construction 14 (the carrier may be made an integral part of the beam construction 14) on which the measuring units 3 are located. With reference to fig. 1A, the one or more rails 10 may be applied at each vertical side parts 1.1, which is particular useful in situations where all the measuring units 3 are to be positioned commonly (as shown in fig. 1). If heavy measuring units are use, it may be preferred to apply e.g. two (or more) rails 10 on each vertical side part 1.1, each of the two (or more) rails extend vertically with a horizontal distance in between.

The carriers 15 are made in such a manner that they engage with the rails allowing the carriers to move only along rails and, preferably, take up bending moments resulting from the gravity acting on the measuring units 2. The rails with carriers may be in the form of longitudinal elongatable pillars, toothed racks or the like.

Alternatively, the mechanically activated position system as disclosed in fig. 8 and 9 may be used to position the measuring units 2 at different vertical positions in the rack frame 1.

Fig. 3 show an example rails 10 arranged at the back of the rack frame - however, the rails in fig. 3 comprises (in relation to the vertical movement) further a second rail system (not shown) for a horizontal movement.

While the rails with carriers allows the measuring units 2 to move up and down, the activation of the movement is produced by a linear actuator connected to the carriers moving the carriers along the rails upwardly and downwardly.

Alternatively, the linear actuator may be a connected to the unit frames 3.

The linear actuator may be in the form of a hydraulic operated piston, a chain drive, a spindle or similar.

As shown in fig. 1, the number of measuring units 2 is three. However any number of measuring units 2 are considered within the scope of the present invention. When more than two measuring units 2 it may be preferred that the mechanically activated position system being configured to position each of the at least one measuring unit 2 individually at different vertical positions in the rack frame 1. This may preferably be provided by the mechanically activated position system for each measuring unit 2 is a separate position system that can be operated independently of the other position system.

In other embodiments, where the number of measuring units is at least two the mechanically activated position system may be configured to position all measuring units 2 commonly at same vertical position in the rack frame. This may be provided by having a single position system and connecting each measuring unit 2 to each other, whereby upon movement of one of the measuring unit 2 will provide a movement of the other connected measuring units 2. Fig. 4 which is a schematically front view of a rack according to a preferred embodiment of the invention is an example where all measuring units are moved upwardly and downwardly commonly.

As seen most evident from e.g. fig. 2A, the measuring unit 2 may each comprising sub-units 4, 5, 6, 7, 8 and one of more one or more of the sub-units are extractable from the unit frame 3. As shown in fig. 2A the upper sub-unit 4 is a drawer in which a number of containers (bottles) are located. These container may comprise one or more fluids, chemicals or the like which either is analysed or used during measuring and/or analysing. The containers comprising lines (not shown) allowing the content of the containers to be extracted by e.g. the equipment located below in each measuring unit 2 and such lines are made from a flexible material allowing the drawer with containers to be drawn out from the measuring unit 2 while still being connected in an operating state to other sub- units of the measuring unit 2. The lines may also be electrical lines to conduct an electrical signal from a analyser arranged in one or more of the containers to one of the sub-units of the measuring unit or to a position outside the rack.

The other elements of the measuring unit may also be drawn out from the unit frame 3. In some embodiments, it is preferred that the measuring units as such can be drawn out from the rack, e.g. in order to service the measuring unit 2. The measuring unit 2 may in this connection be provided with guides cooperating with guides in the rack frame 1 so as to allow for the measuring unit 2 only a horizontal movement out of the rack.

Fig. 1 and 2 also disclose lines 9 from the measuring units to a position outside the rack. Such lines may be for exchanging data with e.g. a central server and each measuring unit 2, for supplying power to the measuring units 2. Also these lines are made flexible so as not to hinder the movement of the measuring units 2 in the rack frame 1. In a particular preferred embodiments, all the all the measuring units 2 in one rack are identical to each other.

Reference is made to fig. 3 disclosing a further embodiment of the invention. As disclosed above, the first rail system 10 provides a vertical movement of the measuring units 2. In the embodiment disclosed in the fig. 3, the mechanically activated position system, to which the unit frame 3 of each of the at least one measuring unit 2 is connected, is further configured to position each of the least one measuring unit 2 at different horizontal positions in the rack frame 1. In the embodiment disclose in fig. 3 no horizontal top part and bottom part is shown. Although such parts may be applied, the top and bottom parts may be dispensed and the vertical sides may be attached directly to the floor. Further, mechanical stiffness to the rack frame may be provided by e.g. the position system(s) and/or e.g. a lattice structure applied to the back of the frame.

It is noted that in fig. 3, the elements 25 is vertical support elements provided for stability purposes at the front of the rack in such a manner that the measuring units 2.1, 2.2, 2.3. 2.4 and 2.5 may moved vertically and horizontally behind the support elements 25.

By this, the measuring units 2 of the rack shown in fig. 3 may change places. For instance, the measuring unit 2.1 (please note that the measuring units e.g. 2.1 actually comprises two measuring units 2 which a structurally connected to form a single unit) may be positioned at the upper right corner of the rack frame 1, where after the measuring units 2.2 and 2.3 may be moved horizontally to the right making space for measuring unit 2.4 to move down and into the lower left corner of the rack frame 1. Thereafter, measuring unit 2.5 may be moved to the upper left corner of the rack frame 1. This may be viewed as carousel movement with an anti-clockwise movement. It is clear that movement may be clockwise. Further, although the movements have been disclosed as rotation, the invention in not considered limited to a rotation.

In a preferred embodiment, the horizontal position of the measuring units is provided by the mechanically activated position system comprising a second rail system extending horizontally (not shown). The second rail system comprising as the first rail system, rails on which carriers are arranged, said carrier are connected to the unit frames 3, the second rail system further comprising a linear actuator connected to the carriers moving the carriers along the rails sidewardly. The carriers are as disclosed in connection with fig. 1 and 2, although the rails and carriers are adapted to allow disengagement and subsequent engagement with the rails when the movement is changed from horizontal to vertical or vice versa. Alternatively, or in combination thereto, the carriers are adapted to disengage and engage with unit frames 3 when movement is changed. It is noted that the horizontal position option may be used with the vertical position option.

All the positioning is controlled by a computer adapted to control inter alia the actuators in response to a control signal received.

As disclosed in fig. 3, it may be preferred that the number of measuring units 2 is uneven and greater than three (in fig. 3, five measuring units are used). In such embodiments the internal width and the internal height of the enclosure of the rack frame 1 each are selected as an integer division of the external width and external height of the unit frame 3 respectively. Is it noted that although this is a "mathematical correct formulae" clearance is often needed to allow the measuring units 2 to move relatively to each other without friction. Such clearance is often in the range 1% of the width of the measuring units' outer dimension and in the formulae above this means that 1% of the width is added to the external with and external height of the unit frame 3. Typically and preferably, a rack according to the present invention is supported on a floor and may further comprising, optionally, a third position system. Such third position system being configured to position the rack frame at different horizontal positions on the floor. Such third position system may be provided to

embodiments with vertical position, horizontal position or a combination thereof of the measuring units 2.

Such third position system may also comprise rails provided in the floor and the rack comprising carrier arranged on the rails. While the carriers used in the measuring units 2 needed to engage with the rails of the first and second position system to keep the units 2 suspended, this may not be needed for the carriers used in the third position system as gravity will have at least a tendency to maintain carriers on the rails. However, it may be preferred to have carriers engaging with the rails to prevent the rack from tilting. As for the first and second position system, the third position system typically comprises an actuator, as disclosed above the first and second position system) for position the rack along the rails. Alternatively, or in combination, the third position system may

comprising wheels abutting the surface of the floor, which wheels may be rotatable by means of an electrical motor.

The carriers used herein may be in the form of slides. As disclosed in fig. 1 and 2 connections, such a data, power, fluid connections, from and to each of the measuring unit(s) is(are) led upwardly from the top of the unit frame and beyond the top the rack frame. The connections, such a data, power, fluid connections, from and to each of the measuring unit(s) is(are) preferably made from flexible materials such as plastic and reinforced plastic, rubber, reinforced rubber or the like. In addition, some or all of the connections may preferably be provided with coupling allowing them to be detached from the measuring equipment and/or at the end distal from the measuring equipment.

Often the use of the measuring equipment requires out-sucking of gasses, such as hazardous gasses from the room inside which the measuring equipment is located. In addition, the atmosphere surrounding the measuring units may need control in order e.g. to maintain the temperature of the measuring units 2. Thus, a rack according to the present invention may further comprising ventilation means for ventilating the measuring units 2.

Reference is made to fig. 6 showing an equipment farm according to the present invention. As disclosed in fig. 6, such an equipment farm may be installed in a room having a front wall 20 in which an access opening 21 to the room is provided, two side walls 22 extending from the front wall 20 and an end wall 23 opposite to the front wall 20. Inside the room a plurality of racks as disclosed above arranged. Please note that in fig. 6, a roof and a part of one of the side walls 22 are not shown in order to reveal the elements inside the room. Further, the room is shown with an access opening in the end wall 23 as well.

In the embodiment of fig. 6, the racks are arranged side by side in a row along one or both side walls, thereby providing a passage extending from the opening and along the front of the racks.

Fig. 7 shows another configuration of an equipment farm according to the present invention. In the embodiment, the racks comprising the third position system and rails are located in the floor (not shown) along the longitudinal extension of the room. As shown in fig. 7A, the racks are arranged back facing back in a row along one of the side walls (if the dimension allows, such a row may also be arranged on the opposite side wall). The two racks at the end of the row is arranged with the back facing towards one of front 20 or end wall 23. Further, a distance of at least the width of the side part of one rack is provided between at least two of the racks.

As noted with reference to fig. 6, please note that in fig. 7, a roof and a part of one of the side walls 22 are not shown in order to reveal the elements inside the room. Further, the room is shown with an access opening in the end wall 23 as well. In addition, a row of cabinets 24 is shown extending along one of the side walls 22.

It is noted that the two racks at the end of the row may not necessarily comprise the position system, as there may be no need for moving the rack horizontally. Each of the racks may be moved independently from each other by third positioning systems in a horizontal direction parallel to the longitudinal direction of the room. This provides the possibility to re-arrange the distance between the rack, e.g. into a configuration as disclosed in fig. 7B. Thereby easy access to each individual measuring unit 2 may be provided by position the rack and/or position a particular measuring unit 2 relatively to the rack in which it is located to position a particular measuring unit in desired position relatively to e.g. an operator. As indicated in fig. 7, as the racks are arranged back facing back, two racks may be connected to each other so as to form a single rack and moved accordingly as a single rack. It is further noted, that the arrangement back facing back may be departed from and the rack may be arranged back facing front.

Reference is made to fig. 8 and 9 showing two further embodiments of a measuring unit according to the present invention; in the figure two measuring units are shown but at different altitude,

As seen from fig. 8, the measuring unit comprising a unit frame 3 comprising two vertical side parts, a horizontal top and bottom parts, in which unit frame 3 measuring equipment of the measuring unit 2 is arranged as disclosed above.

In the embodiments of fig. 8 and 9, the unit frame 3 of the measuring unit 2 is connected to a mechanically activated position system 11. The mechanically activated position system is configured to position each of the least one

measuring unit 2 at different vertical positions. This is shown in fig. 8 (and 9) by the two measuring units being located at different vertical positions (altitude). It is noted that the measuring units 2 may be positioned according to choice.

In the embodiments of fig. 8 and 9, the mechanically activated position system comprising a longitudinal elongatable pillar 11, such as an elongateable actuator (also know as a lifting column), preferably in the form of an hydraulic cylinder.

The elogatable pillar 11 is connected at one end to the bottom part of the unit frame 3 and wherein the longitudinal direction of the pillar is parallel to the longitudinal direction of the vertical side parts. This means with reference to fig. 8 and 9 that the pillar 11 extending parallel to gravity and is elongatable to raise the measuring unit 2 from a ground position upwardly to an upper most position.

In a further embodiment, the mechanically activated positioning system may further be configured for moving the unit frame 3 in a horizontal direction, preferably being limited to a forward and backward movement (where forward refers to the direction out of plane in fig. 8). Such a configuration may be provided by arranging the horizontal bottom part on horizontal rails (not shown) in a vertically locked mode so that the unit frame 3 can be moved horizontally along the rails, while the vertical movement is not hindered.

Such horizontal movement may requires that the lower end of the mechanically activated positioning system is secured to the floor in order to avoid tilting of the measuring unit.

In a further embodiment, see fig. 9, the longitudinal elongatable pillar 11 comprising, at the end being distal to the one being connected to the bottom of the unit frame 3, a horizontal position system 12 configured to position the measuring unit 2 with pillar at different horizontal positions on a floor. In the embodiment shown in fig. 9, the horizontal position system 12 comprising four wheels providing a possibility for the measuring unit with pillar to be rolled along the floor on which it is located. The wheelbase (the distance between centre of the front wheel and the centre of the rear wheel) and the track (the distance between the centre of two front wheel or the two rear wheel) are both preferably larger than size of the bottom part 3.3 in order to increase the stability of the measuring unit during horizontal movement. It is noted that the rail with carriers disclosed herein may substitute the wheels. Although the embodiment of fig. 9 indicates that the horizontal movement is limited to a forward -backward movement, this may not be the case as suitable wheels may be applied if further movements are desired. Further, the wheels may be driven by electrical motors allowing for a smooth moving of the measuring unit.

It is noted, that in the embodiment using elongatable pillar, a carrier is typically consider present as the part pillar moving and carrying the measuring unit. As also shown in fig. 8 and 9, a measuring unit according to the present invention may comprise a void 17 for storing e.g. bottle or other containers for consumables or discharge used or produced during use of the measuring equipment. Typically, such a void 17 may be in the form of a drawer arranged in the unit frame and which can be extracted partly or fully from the unit frame to allow access to the content stored in the void 17. The void 17 is preferably ventilated by sucking air (or in general gas) from the void and e.g. to the exterior (as disclosed below in connection with e.g. fig. 13). In some preferred embodiments, the void 17 at the upper end of the measuring unit stores consumables, whereas the void 17' at the lower end of the measuring unit stores discharge fluid.

Further, a measuring unit according to the present invention may comprise a further drawer (not shown) containing a tool-kit for tools to be used e.g. during use of the measuring unit. This drawer is typically configured with a cover which covers the tools and may be used as table during use of the measuring unit e.g. for temporarily storing a laptop.

In equipment according to the present invention, some or all of the racks (e.g. as disclosed in connection with fig. 6 and 7), may be interchanged with the measuring units 2 as disclosed schematically in fig. 8 and 9.

Reference is made to fig. 10 which shows schematically a 3 dimensional view of a measuring unit 2 according to yet another embodiment of the invention. The measuring unit 2 comprising three measuring unit sections 13.1, 13.2 and 13.3. It is noted that the two sections 13.1 and 13.3 are structural identical to each other - preferably by being configured to contain the same number and type of measuring equipment (15) - except from connections to e.q. power and the bottles contained in section 13.2 may be different to. Further, in fig. 10, the measuring equipment 15 shown in the section 13.1 left hand side are removed in the section 13.1 right hand side. Still further, one of the sections 13.1 or 13.3 may be omitted and/or the sections may be arranged in a different order than what is disclosed in fig. 10 (e.g. in the order from left to right: 13.1; 13.3; 13.2).

The three sections 13.1 13.2 and 13.3 are preferably assembled (preferably by mutually attaching the three section to each other) into a measuring unit 2 and a positioning system 11 e.g. as disclosed in connection with fig. 8 is preferably arranged to positioning all three sections simultaneous at different vertical positions. However, each of the sections 13.1, 13.2 and 13.3 may be individual sections (e.g. by not being mutually attached to each other) and may be provided with a positioning system 11 as disclosed in connection with fig. 8 whereby each of the sections 13.1, 13.2 and 13.3 may be arranged at different vertical positions individually. Alternatively or in combination thereto, the sections 13.1, 13.2 and 13.3 may be arranged in a rack frame 1 as disclosed e.g. in connection with fig. 1. Finally, the positioning system may comprise means such that one or more of the sections, such as all of the sections 13.1, 13.2 and 13.3 may be displaced in horizontal direction normal to the front of a section (by front is preferably meant the side of a section facing towards the user during operation of the equipment). Such positioning system(s) is(are) omitted from the fig.s 10-12 for clarity reason only.

As indicated in fig. 10, the section 13.2 contains two voids 17 storing containers, such as bottles, in which liquids used by and/or produced by the measuring equipment are stored. The sections 13.1 and 13.3 are arranged neighbouring the section 13.2 and contain flexible lines (not shown) allowing the measuring equipment to extract and/or deliver liquid to the bottles stored in the voids 17. Reference is made to fig. 11. As shown in fig. 11, some of the measuring equipment 15 in sections 13.1 and 13.3 are arranged in manner allowing them to be drawn out from the measuring unit. In fig. 11, the measuring equipment of the section 13.3 are omitted for clarity reason only. As shown in fig. 11, two measuring equipment 15.1 and 15.2 are drawn out from the measuring unit and one of the measuring equipment 15.2are further turned along a vertical axis.

Thereby, easy access to both the measuring equipment 15.1 and 15.2 is provided in a manner allowing also access to the side of a measuring equipment which when arranged in the measuring unit in a non-drawn out manner are arranged closely side-by-side (as shown in fig. 10, e.g.).

As disclosed herein, a measuring unit preferably refers to a stand-alone unit.

Thus, each of the measuring unit sections 13.1, 13.2 and 13.3 may each be considered a measuring unit e.g. if configured to operate as a stand-alone unit providing a measuring or analysis result without input from other measuring units. Reference is made to fig. 12 and left hand side measuring unit section 13.1, which shows the configuration of fig. 11 with the measuring equipment 15.1 and 15.2 omitted. In fig. 11, the measuring equipment 15.1 and 15.2 are shown in an extracted position. As shown in fig. 12, the measuring unit comprises a supporting plate 18 arranged on rails 10 for carrying the supporting plate 18 supporting the measuring equipment while at same time allow the supporting plate 18 to move horizontally and thereby also provide a horizontal movement of the measuring equipment. The measuring unit further comprising a rotatable receptacle 19 adapted to support a measuring equipment and allow rotation of the rotatable receptacle 19 along a vertical axis. As shown in fig. 11 and 12, the two

neighbouring measuring unit sections 13.1 and 13.3 are structurally identical to each other while the middle measuring unit section 13.2 is more narrow and contains to voids 17 for storing bottles (see also fig. 10). As shown in fig.s 11 and 12 the rotatable receptacle 19 is extractable from the measuring unit so as to allow the receptacle 19 (and thereby the equipment contained in the receptacle) can be extracted from the measuring unit and rotated to a position e.g. in front of the measuring unit section 13.2. This may be provided by arranging the receptacle 19 on the support plate 18 or on a separate set of rails.

It is further noted, that the rack frame may be constituted fully or partly by the mechanically activated position system(s). For instance, the rails or position systems in general used for providing vertical and horizontal movement may be used to provide the structural stiffness of the rack and which rails or position systems is/are arranged at the back of the measuring units, whereby one of or all of the two vertical side parts, the top part and the bottom part may be omitted.

As indicated herein, each of the measuring unit may advantageously be

equipment with a ventilation system for ventilating the measuring units. Such ventilation system may be in the form of one of more pumps which sucks out gasses produced by the measuring equipment and may advantageously be connected at the outlet to lines arranged to lead the gasses sucked out to a predefined position, such as to the atmosphere outside a building or to a treatment facility for removing hazardous substances from the gasses. Fig. 13 illustrates schematically a cross sectional view of a measuring unit 2 according to the present invention. The measuring unit 2 being equipped with a ventilation system 26, comprising two channels 27 being provided with two valves 29 for controlling the fluid flow through the channel and thereby at least partly the ventilation of the measuring unit 2. The valves 29 may are adapted to constrain the flow through the channel between closed channel and unrestricted channel. A pump is provided to provide a force suction of fluid out from the measuring unit, which pump may be arranged in the heat exchanger unit 30 (the pump is not shown in the figure for clarity reasons only).

The channel 29 is connected to upper void 17 containing e.g. containers storing liquid (the connections from the containers are left out for clarity only) and is intended to ventilate the upper void 17. As shown in fig. 13, the channel 29 is also connected to the lower void 17 and is thereby also intended to ventilate the lower void 17. By controlling the valves 29, the amount of air sucked from respectively upper or lower void 17 may be regulated.

The section of the measuring unit 2 containing the measuring equipment 15 is connected at a lower end to the channel 27, as the substances intended to be sucked out is heavier than atmospheric air. If the substances is lighter the atmospheric air, the connection to the channel 27 may be provided at an upper end of the section. Similarly, the connections to the upper and lower voids 17 may be made in accordance with these considerations. Both the channels 27 and 28 are at their upper ends connected to a heat exchanger unit 30 which regulates the heat exchange and mass flow so that a volume fraction x (being between 5 and 95%) of the air sucked out from the measuring unit 2 goes to the outside of the building in which the measuring unit is placed in and the remaining amount goes to the inside of the building in which the measuring unit is placed. The heat exchanger unit 30 regulates the temperature of the two airstreams out from the heat exchanger to have specified

temperatures, e.g. the stream going to the inside having a temperature of e.g. 20°C and the stream going to the outside having a temperature of e.g. 70°C. If needed, the heat exchanger may comprise a heat pump. Further, is desired, the high temperature stream may be used for heating purposes prior to be sent to the outside.

While it may be preferred to provide two channels 26 and 27, a measuring unit according to the present invention may comprise a single channel extending along the back-side of the measuring unit. Further, in embodiment where the

mechanically activated positioning system is configured for both a vertical positioning and a horizontal positioning, the channel may be arranged in a fixed horizontal position (while allowing it to move vertically along with the positioning system for vertically movement) whereby the channels are disconnected from the unit frame when the unit frame is moved horizontally.

Reference is made to figure 14 illustrating schematically a measuring unit 2 according to a preferred embodiment of the present invention in which the mechanically activated position system is configured to provide a vertical and horizontal movement of the measuring unit 2. Figure 14 shows three identical measuring units 2 being arranged in different positions: the measuring unit 2 in the left hand of fig. 14 is moved horizontally forward, the measuring unit 2 in the middle figure of fig. 14 is in its most backward position (which typically is position in which the measuring unit is used to measuring) and the measuring unit 2 in the right hand side of fig. 14 is in its operation mode.

As illustrated in fig. 14, the mechanically activated position system comprising the part 11 (preferably in the form of an elongatable pillar) which moves the measuring up and down when activated and the part 12 moving the measuring unit 2 horizontally when activated. The part 12 is preferably made by rails on which the unit frame is slidingly arranged or an horizontal arranged elongatable pillar. The embodiment shown in fig. 14 further comprising a ventilation system 26. The ventilation system 26 comprise a vertical extending channel 26.1 (extending behind measuring unit 2). The ventilation system further comprising one or more horizontally extending channel 26.2 in fluid communication with vertical extending channel 26.1. The horizontally extending channel extends into e.g. the void 17 when the measuring unit 2 is in its most backward position. Gas is sucked by use of a pump (not illustrated) sucking gas from e.g. the void 17 through the horizontally channel 26.2 towards and through the vertically channel 26.1

The void 17 in fig. 14 is embodied as a drawer which is shown in its extracted position in the middle part of fig. 14.

Reference is made to figure 15 illustrating schematically a measuring unit according a preferred embodiment of the invention. Figure 15 illustrates a single measuring 2 in three different positions: left hand side with the void 17 in the form of a drawer extracted; the middle of fig. 15 where the measuring unit 2 is moved forward, and the right hand side where measuring equipment 15.1 and 15.2 are extracted from the measuring unit as disclosed in relation to e.g. fig. 11 herein. The measuring unit comprising a ventilation system 26 having a vertically extending channel 26.1 (extending along the back of the unit 2). The vertically extending channel 26.1 is connected to a horizontally extending channel 26.2 arranged in fluid communication with the void 17 (storing e.g. bottles with liquid). A pump (not illustrated) is arranged to suck gas out from the void measuring via the vertically and horizontally arranged channels 26.1 and 26.2. As also indicated in the figure, a ventilation 26.3 channel is arranged separate from the channels 26.1 and 26.2 and is configured for ventilating the elements of the measuring unit 2 not producing gasses but requires e.g. ventilation to conduct heat away from the measuring unit 2. By such a separation, warm air can be sucked out from the measuring unit 2 and e.g. distributed to the room in which the measuring unit 2 is arranged.
