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.
