EXD170 Infrared Combustible Gas Detector Unit

Feature & Principle

It operates based on non-dispersive infrared absorption principle. The target gas absorbs specific infrared wavelength, the photoelectric receiver converts light attenuation into concentration signal. Built-in temperature compensation suppresses drift, supports 4-20mA and digital communication for gas alarm and interlock.
