GRG5HInfrared carbon dioxide sensor 

 This product USES the international advanced non-dispersive infrared detection technology, overcome the principle of thermal catalytic sensor calibration cycle is short, easy to poisoning, and by adopting the technology of embedded microcontroller controller, the built-in precise temperature compensation circuit the measuring accuracy will not drift due to temperature change. The instrument has the measuring accuracy, fast response speed, calibration cycle is long, is not affected by other gases, wide measuring range, low power consumption, long service life, stable performance, high reliability, etc. The instrument can be set up via the remote control is convenient working point, at the same time the output of 200 ~ 1000 hz frequency signal and the RS - 485 digital signal, convenience and various types of supporting the use of coal mine safety monitoring system.

Mainly applied to the coal mine mining working face, return air roadway, a gas explosion gas environments, such as mechanical and electronic chamber for continuous measurement of gas concentration. This instrument has the determination, according to the gas instantaneous concentration, transfinite alarm and output power control, infrared remote control signal calibration, digital communications, and other functions.
