When measuring oxygen in the presence of helium, helium
compensation can be used. The option of helium
compensation is no certified measuring function according to
EN 50104.
CAUTION
Sensor failure
The exposure of the sensor to higher concentrations of
unsaturated hydrocarbons, alcohols, or hydrogen over an
extended period of time (dose approx. 100,000 ppm x hours)
can cause the instrument to fail.
► Ensure that the sensor is not exposed to such
concentrations over an extended period of time.
