For this purpose it uses a catalytic sensor which 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 ventilationair conditioning installations & 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.
