Zero calibration: Establishes sensor(s) baseline reading, % oxygen and free of any toxic or combustible gas vapors. To maintain a stable baseline, it is essential to perform zero calibration in fresh air. In the event, fresh air cannot be confirmed, use zero grade air or N2 to perform a detector zero calibration. Perform a zero calibration to reestablish baseline as required, and before a ...

The sensor response to CH4 , H2 , CO, and NH3 . The response of the semiconducting metal-oxide layer to different gases is shown in Fig. 1. It follows from an analysis of these curves and a correlation of the gas concentrations that the response to CO and CH4 is rather fast in comparison with that to NH3 . Moreover, the conductivity maximum on the response curve for different gases varies in ...
