19 Cross Interference and Cross Calibration
19.1 Cross Interference Table for Toxic and Oxygen
This below table shows the relative cross sensitivity of the Sensepoint XCD to other
gases. “Gas Type” indicated the XCD sensor type fitted to the XCD. “Gas Type Applied”
indicates the gas that may be applied to that sensor and the resulting Reading.
