Det-Tronics PIRECLA4A3W PointWatch Eclipse IR Gas Detector Unit

Feature & Principle

It adopts non-dispersive infrared (NDIR) absorption principle. The infrared light source passes through the measurement chamber, hydrocarbon gas absorbs specific wavelength light, the photoelectric receiver detects light attenuation and converts it into gas concentration signal. Built-in temperature compensation, anti-interference algorithm reduces false alarms, supports HART digital communication and 4-20mA analog output for gas interlock protection.
