SCM4 – Carbon Monoxide Detector Get real-time results. Field-replaceable CO sensorCalibrate to ambient quickly with the ZERO buttonAudio/visual alarms with muteFast electro-chemical sensorMagnetic hanger for hands free The SCM4 Carbon Monoxide (CO) Detector has a very fast reaction time, and measures CO in parts per million (ppm). Its electrochemical sensor is fast enough for walk-around tests. Features and benefits include: Field-replaceable CO sensor; Advanced three-pin sensor measures 0 to 1000 ppm CO; Calibrate / Zero SCM4 to ambient quickly with the ZERO button; Audio and visual alarms w/mute; Bright-blue, backlit dual-display with MAX and real-time measurements displayed; Magnetic hanger for hands-free operation; Auto Power-Off (APO). The “Walk-Around” Test: The SCM4 responds to changes in CO levels in real time. Zero the unit outdoors away from any source of CO (will not zero if CO levels are higher than 5ppm) Enter the structure Walk around and watch the display Move to
