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 C₂H_2,CH_4,C₄H_10,C₂H_4,C₂H6, C₃H_8,CO₂_,CO and SF₆, etc.

PGas-31 gas infrared quantitative detector is mainly composed of two parts: the host machine and hand-held probe.
