Detailed 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.
Main features
The probe unit adopts light-emitting display screen of organic matter, it is self-luminous with low power consumption and high brightness, and there is no problem of visual angle
The host machine adopts 3.5 inch color touch display screen, the brightness is high, the visual angle is small and the contrast is adjustable
The sensitivity is high, the detection of leakage can reach 0.1 ppm, and the precision can reach 1ppm at most
Good stability
Swift response time
Acoustoptic alarm
Facilitates carrying;
It can realize manual storage of measurement data;
Long service life of sensor
