CO (CARBON MONOXIDE) MODE

7.4.3 Air-Free CO

Air-free CO is the CO reading modified by the O

reading,

therefore this measurement will only be available when

an O

sensor is fitted. The purpose is to determine whether

or not the emissions from an un-ventilated appliance,

principally an oven or a stove / cooker, are safe.

This is the CO reading modified by the O

reading

(only applicable if O

sensor is fitted).

CO Air-free = (20.9 x CO) / ( 20.9  O

The typical display for this mode is shown in Fig. 7.5:

A sample is considered invalid until the Oxygen (O

)

concentration is below 19% Vol.
