Fieldpiece SCM4 Carbon Monoxide Detector

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 SCM3 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); Use optional pump (AOXP2) for remote / flue gas testing.

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
• 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
• 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
• Use with optional AOXP2 pump for flue gas testing
