PGas-31 Infrared Gas Detector
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.
1. Display screen of host machine
2. Host machine
3. Power switch
4. Aviation plug
5. Filter cap
6. Probe rod
7. Probe panel
8. Probe
9. Communication wire
