CO2 Gas Detector
1. NDIR principle
2. good stability and sensitivity
3.high precision
CO2 Gas Detector
1.The measurement principle of (NDIR)" Non-dispersive Dual-wavelength Infrared Spectrum" is adopted for PGas-31 gas infrared quantitative detector.
2.There is no radiotive emitter and it is convenient to carry; the screen of hand-held probe uses OLED,
3.it is selfluminous with high brightness, with no visual angle problem; high precision, good stability and sensitivity, and the resolution of leakage detection can reach 1ppm;
4.the response time is fast; with no consumable parts, life time of the sensor is extra long; it can detect gases include C2H2,CH4,C4H10,C2H4,C2H6, C3H8,CO2,CO and SF6, etc.
