The AQM-103 is designed to measure CO concentration and air temperature with visible and audible alarms. This CO monitor is an ideal instrument for indoor air quality (IAQ) diagnosis and HVAC system performance verification.
CO is a common byproduct of the combustion of fossil fuels. Carbon monoxide or CO is a colorless, odorless and tasteless gas. Due to this fact, it is very hard to detect the presence of CO in your environment. It is, however, imperative that the CO levels are carefully monitored. Even at relatively low levels, CO is poisonous because it rapidly accumulates in the blood thereby depleting its ability to carry oxygen. Extreme cases of CO poisoning result in death.
For healthy adults CO becomes toxic when it reaches a level higher than 35 ppm (parts per million) with continuous exposure over an eight hour period.

It's OK.As delivered it said even fresh outdoor air was @ 25ppm CO. After re-zero-ing, it now says indoor air is between 0 and 15ppm CO (constantly wandering in this range, even if our furnace and gas stove are completely shut down). It is not quite as accurate as I was hoping for.
