Carbon Monoxide (CO) gas is poisonous to humans at certain concentrations. OSHA limits extended work periods in concentrations above 50ppm while a concentration of 667ppm can lead to seizures, coma or even death. This meter is a great way to check carbon monoxide levels in any environment. This meter is invaluable whether it is at home testing a hot water heater or furnace or industrial environments where CO gas can accumulate to dangerous levels.

With a range from 0 to 1000ppm this meter will test any acceptable healthy range and far past into dangerous ranges. This meter can easily detect dangerous levels of CO accurately thanks to its ability to zero itself on start up and its utilization of a stabilized electrochemical gas specific (CO) fast response sensor. With an audible alarm above 35ppm for safe testing. The CO10 Carbon Monoxide CO Meter User Manual is attached to this page to answer any additional questions.
