Detect the presence of carbon monoxide (CO) in ambient air with Martindale's CO90!

Designed for use in any environment with a risk of high concentrations of carbon monoxide, the CO90 can detect CO levels up to 1999ppm and alerts the user to increasing CO concentration by using an audible beeping tone that will speed up as the carbon monoxide level increases. Once the level increases above 200ppm the audible indicator will become a continuous tone.

CO ppm concentration levels are also shown on the detector's built-in LCD screen as a digital reading. This value can be temporarily frozen using the data hold function or the maximum value taken over a period of time can be displayed by using the built-in MAX feature.
