The Carbon Monoxide Meter Detects the Presence of carbon Monoxide (Co) and Measures concentration between 1-1000 parts per million (PPM).

The Meter indicates the presence of carbon monoxide in two ways:

• By a reading on the LCD in PPM.

• By a beeper tone.

When the measuring data is more than 30ppm and less than 200ppm, the meter will warm with discontinuity beeper, when the measuring datum is over 200ppm, the unit will warm with continuity beeper.

In both cases, the alarm light glows with red light.
