Checking carbon monoxide levels is as easy as pushing just one button with the Extech C010. This meter can measure CO levels up to 1,000 ppm with a resolution of 1 ppm and ±5% or ±10 ppm basic accuracy (whichever is greater). The CO10 sounds an alarm starting at 35 ppm that increases in speed at higher concentrations of CO. Above 200 ppm, the alarm will sound continuously. Additional features include a backlight on the display that can be used in low light areas, max hold, data hold, and auto-power-off. The meter comes complete with a 9-volt battery, protective holster, and case.
