    Combustible gas detector model CRH-80D is fixed combustible gas detector used a non-intrusive sensor designed to detect and monitor combustible hydrocarbon gases in air over the range of 0-100%LEL using miniature non-dispersive Infrared Optical (NDIR) sensor technology. As compared to catalytic bead sensors, with NDIR there is no risk of sensor poisoning, no risk of high concentration saturation, and no need for O2 to be present. This infrared combustible gas detector is equipped with standard analog 4-20mA, and Modbus RS-485 outputs. Additional integration options include a remote controller, audible-visual alarm, control panel. Infrared combustible gas sensor has an infinite shelf life and is supported by a 5-year warranty.

    Features:

    LED Display (audible-visual alarm);

    Non-intrusive Interface;

    Auto Zero/Auto Span;

    Pre-emptive Fault Diagnostics;
