NOTICE
Sensor failure
The sensor cannot be used for Oxygen measurements in the presence of Helium!
Do not use the sensor for Oxygen measurements in the presence of Helium.
CAUTION
Sensor failure
The exposure to higher concentrations of unsaturated hydrocarbons, alcohols or
hydrogen over an extended period of time (dose approx. 100,000 ppm x hours)
could cause the sensor to fail.
Ensure that the sensor is not exposed to such concentrations over an extended
period of time.
