CH4 methane sensor CM1108UL-CH4

NDIRfor leak detectionmonitoring

Product Overview
Cubic CM1108UL-CH4 is a super low power NDIR methane (CH4) sensor specifically designed for battery-powered and portable gas detection applications.

CM1108UL-CH4 incorporates a super low power consumption design, and the average working current can be less than 30 μA. By adopting advanced non-dispersive infrared (NDIR) technology, the sensor delivers high accuracy and long-term measurement stability across its full detection range of 0–5% Vol. Matrix calibration across whole temperature and concentration range ensures consistent performance under varying ambient conditions, while the built-in auto-calibration function eliminates the need for routine maintenance. The sensor has a long lifespan of more than 10 years.

With the features of low power consumption, high accuracy, maintenance-free operation, and compact design, the CM1108UL-CH4 is ideally suited for battery-powered gas detectors, portable instruments, and other applications requiring reliable methane detection with minimal energy consumption.
