Carbon monoxide meter detects the presence of carbon monoxide (CO) and measures concentrations between on to 1,000 parts per million (PPM)The meter indicates the presence of CO by a reading on the LCD and a beep tone The beeper function much like clicking of a Geiger counter: above 200PPM, the beeper sounds continuously with the concentration of COFrom 35 to 200PPM, the beeper sounds discontinuously with the concentration of COFeatures:<

Digital LCD display Auto/manual zero Memory for 10 complete data sets Record mode Red and blue LED light audible alarm High accuracy, quick response Pocket size and easy to use Fast sampling Data hold Above 200PPM, the beeper sounds continuously
