Title:
DEVICE FOR MEASURING THE AMOUNT OF OXYGEN PRESENT IN A GAS
Document Type and Number:
WIPO Patent Application WO/2018/127667
Kind Code:
A3
Abstract:
The present invention relates to a measurement device (1) for measuring the amount of oxygen present in a gas to be analysed, said device (1) comprising: at least one measurement member (3) for measuring the amount of oxygen, a first inlet (5) in communication with the measurement member (3) in order to supply gas to be analysed, and an outlet (7) through which the analysed gas is released. According to the invention, the device (1) comprises a second gas inlet (6), in communication with the measurement member (3), for selectively supplying the device (1) with a standard gas containing a known amount of oxygen, such that the measurement of the amount of oxygen present in the standard gas can be used to determine a possible drift in the measurement obtained by the measurement member (3) relative to the real amount of oxygen known to be present in the standard gas.
