│ 2 Product description
Technical information about the sensors, including their meas-
urement ranges, can be found in section 9.2.
Information about electrochemical sensors
Very high gas concentrations can reduce the lifetime of electro-
chemical sensors.
Information about semiconductor sensors and catalytic
combustion sensors
These sensors are sensitive to external influences.
− Oxygen-deficient atmospheres can reduce the sensitivity of the
sensor (sensor suffocation).
−
Gaseous components of silicones, oils and phosphate esters
etc. can irreversibly damage the sensor.
−
Contamination of the measuring environment with halogens,
burnt neoprene, PVC, trichloroethylene etc. will also reduce
the sensitivity of the sensor. However, the sensor can usually
regenerate itself during further operation.
