Infrared carbon dioxide sensor GRG5H GRG5H infrared carbon dioxide sensor GRG5H infrared carbon dioxide sensor (hereinafter referred to as the sensor) is to meet the carbon dioxide concentration of coal mine monitoring needs and developed. It can continuously and automatically converted into the underground carbon dioxide concentration is connected with standard electrical signal transmission to the device, and has a local display gas concentration, overrun sound and light alarm. Sensor proof test by the state authorities for online examination, can be used with all types of domestic monitoring systems and power meter, gas locking devices supporting wind power, suitable for coal mining face, electromechanical chamber, back to the wind tunnel and other locations stationary use.
