TThe 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 toward the area of highest concentration to find the CO source

The SCM4 Carbon Monoxide Detector (CO Detector) offers several features and benefits to field technicians: Field-replaceable CO sensor

• • Easy to install
• • Lasts approximately two years
• • Comes pre-calibrated
• • Fast electrochemical sensor helps you find CO sources like cracked heat exchangers or breached flue stacks
• • Calibrate to ambient quickly with ZERO button
• • Audio and visual alarms (with MUTE function)
• • Alarm rate increases as carbon monoxide concentration increases MAX hold to help you zero in on the source
• • Bright-blue backlit dual-display to test in dark crawl spaces
• • Magnetic hanger for hands free testing
• • Auto Power Off (APO) to save battery life (easy to disable)
• • Battery check with % of battery life left displayed
