G4-CH4 Infrared Methane Gas Sensor Is Explosion-proof And Oxygen-freeFor Measuring Instruments
Features:
G4 infrared gas sensor is an intelligent micro gas sensor designed based on the NDIR principle. It uses gas to measure the concentration of specific infrared spectrum absorption characteristics. It is designed in accordance with dual wavelength optical path, without oxygen dependence and catalytic poisoning of the sensor, with long life, high accuracy and stable performance. The sensor has analog and digital signal output interfaces, which can directly output the gas concentration value signal through linearization and temperature compensation, and is easier to use.
• High resolution, 0-10%VOL range resolution is 0.01%, 10%-100% VOL range resolution is 0.1%
• Range up to 0-100% VOL
• Linear, temperature compensated data output
• Digital and analog signal output
• Wide temperature range from -40℃ to 70℃
• Long-term stability, easy calibration
• No "poisoning" of catalytic sensors
• No oxygen dependence
• Intrinsic safety explosion-proof
• Dual wavelength optical path design
