Field-replaceable CO sensor
Calibrate to ambient quickly with the ZERO button
Audio/visual alarms with mute
Fast electro-chemical sensor
Magnetic 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 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
