Principle of Operation
The
lion alcolmeter
®
700
uses an electrochemical fuel cell sensor to
measure the concentration of alcohol vapour
in the subject’s expired
breath, a measured amount of which is drawn from the mouthpiece into
the fuel cell by means of the sampling system.
In the fuel cell a voltage is generated in proportion to the breath alcohol
concentration: it is therefore amplified and displayed in terms of the
subject’s alcohol level.
