SCM4, Carbon Monoxide Detector

Overview: 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. Carbon monoxide (CO), a product of combustion, is an odorless, colorless gas. Faulty combustion equipment is one source of this dangerous gas known as the "silent killer". How Does it Work? The "Walk-Around" Test: The SCM4 responds to changes in CO levels in real time. You must find the source of CO when levels rise on entry into a structure. 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 Persistent sources of CO, such as malfunctioning combustion equipment in occupied spaces, must be serviced immediately. Features and Benefits: 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 What's Included: SCM4 Carbon Monoxide Detector (CO Detector) 9V battery (installed) Operator's manual For additional technical specifications, please see "User Guide" in the manuals tab.
