Detect CO fast. Work faster.
Our SCM4 Carbon Monoxide (CO) Detector quickly checks the air and instantly tells you the CO parts per million (PPM) in real-time. A detector like this is sensitive and fast enough for you to quickly perform walk-around tests. Its advanced three-pin sensor is field-replaceable and allows you to calibrate to zero instantly for easily finding the highest CO concentrations.
Tough and easy to use.
The SCM4’s rugged case holds a bright-blue dual-display that’s easy to read in any light. The backlit screen shows real-time measurements and the detector includes audio and visual alarms. The case also includes a magnetic hanger for easy hands-free use.
