G4 infrared sensor is designed with NDIR technology to monitor the presence of gases and vapours via their infrared spectral properties. The sensor which features long life, high percision and stable performance operates independent of oxygen and is immune from pellistor poisoning. With two output formats (analogue output and digital output) and the linear, temperature compensated signal proportional to the gas concentration, the sensor is very easy to use.
APPLICATIONS
G4 infrared sensor is used to detect the concentration of gases, such as carbon dioxide, methane and other hydrocarbons. It meets the requirements of GB 15322-2003, AQ 6211-2008, AQ 1052-2008 and other relative standards. It applys to all industrial environment health and safety inspection, including chemistry & petrochemistry, electric power & energy, mining, metallurgy, gas Extraction and more.
