Product Description
Brief introduction
The measurement principle of (NDIR) "Non-dispersive Dual-wavelength Infrared Spectrum" is adopted for PGas-31 gas infrared quantitative detector. There is no radiotive emitter and it is convenient to carry; the screen of hand-held probe uses OLED, it is self-luminous with high brightness, with no visual angle problem; high precision, good stability and sensitivity, and the resolution of leakage detection can reach 0.1ppm; 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.
PGas-31 gas infrared quantitative detector is mainly composed of two parts: the host machine and hand-held probe.
