The breath sampling system is factory-set to sample deep-lung air; it is the
breath from the bottom of the lungs that truly reflects the amount of
alcohol in the body.
To ensure repeatable and accurate results across the temperature range,
and particularly at low temperatures, the lion alcolmeter
®
900 uses a
heater to heat the metal sampling port and the inlet port of the fuel cell.
This prevents the build-up of condensation, which can affect the alcohol
concentration in the sample.
