AEMC 2121.35 - Carbon Monoxide Meter Model CA895

The Carbon Monoxide Meter Model CA895 measures the level of carbon monoxide present in the surrounding atmosphere from 0 to 1000ppm. For this purpose, it uses a catalytic sensor that does not consume any chemical substance. This portable instrument is particularly suitable for detecting levels of CO potentially dangerous for human beings in heating, refrigeration, ventilation/air-conditioning installations, and, in general, in industrial, commercial, or residential environments where combustion gas may accumulate.

The most common use is to locate the source giving off the CO, facilitated by the presence of a buzzer, the frequency of which increases with the concentration of the CO. Above a level of 200ppm, the buzzer makes a continuous sound.
