2. General Description
The Carbon Monoxide Meter is designed with a high accuracy CO sensor, providing high accuracy,
fast response and stable readings. It is used to detect the presence of carbon monoxide in wide
applications:
Poorly maintained furnaces, gas heaters, or fireplaces.
Dirty or plugged chimneys, or flue exhausts.
Poorly maintained gas, oil, or kerosene appliances.
Internal combustion engines (e.g., automobiles, lawnmowers, blowers).
The Meter indicates the presence of CO by a reading on the LCD and a beeper tone. The
beeper functions much like clicking of a Geiger counter:
Above 200 PPM, the beeper sounds continuously with the concentration of CO.
From 35 PPM to 200 PPM, the beeper sounds discontinuously with the concentration of
CO.
