Interferent Notes

(*) Long term exposure may damage sensor.

(***) means the substance is not combustible in air under normal conditions. “C” Denotes a ceiling (in TLV column).

If an interferent is present and there is no target gas, certain transmitters will not display the interferent response until the EFFECT of the interferent reaches

± 4 ppm. This is due to display “blanking” that occurs between -3 ppm and + 3 ppm on transmitters that display gas concentrations as whole numbers (no decimals
