CO2 Gas Detection Calibration Technologies

A sensor near a CO2 source can result in unusually high readings. Choosing Alarm set points and actions for CO2: The typical CO2 Gas Sensor for process leak detection should be ranged of 03% CO2, with a warning setpoint at % (8 Hour TWA allowable exposure) and an alarm setpoint at % (15 minute STEL) CO2.

Why is hydrogen such a big issue for CO sensors? | GfG ...

The higher the specificity of the sensor, the less likely the sensor will be affected by other gases. The composition of the electrodes and type of electrolyte, as well as the use of selective filters for the removal of interfering gases are all ways to increase the specificity of the sensor. For instance, on the inside, a CO sensor is very similar to a sensor used to measure H2S. The trick is ...
