Title:
WATER QUALITY MONITORING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/053193
Kind Code:
A1
Abstract:
A water quality monitoring apparatus is provided having an air quality analysis unit for detecting using an ion mobility sensor the air quality in a region at least partially enclosed by a wall and a boundary surface with the water the quality of which is to be monitored, and an alarm unit for outputting a signal indicating an abnormality when an air quality pattern obtained from the air quality analysis unit is outside of an acceptable range for an air quality pattern for the air making contact with the water to be monitored. This water quality monitoring apparatus can indirectly yet precisely monitor the water quality of, for example, drinking water inside a water tank by detecting using an ion mobility sensor the quality of the air making contact with the water.
