The instrument contains a gas specific generator cell. Depending on the type of gas, the generator will produce, either electrochemically or thermally, a gas concentration above the TLV1-level. The response of a gas detector can be checked with the small gas concentration produced by the gas generator. However, since the gas generator does not produce a certifiable known gas concentration, it is not suitable for detector calibration. 3.2 How To Run a Gas Test • Insert the sensor of the gas detec
