PGAS-31 Portable Infrared Methane CH4 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 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 Infrared Gas Detector is mainly composed of two parts: the host machine and hand-held probe, as shown in the picture as below:
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
Hand-held probe is embedded with microcontroller, besides the function of gas sampling, detecting and displaying the concentration of gas, the controller also have functions of calibration, alarm value setting and acoustooptic alarm, etc., the operation is simple and the using is convenient. The hand-held probe is connected with the host machine through a cable to transfer the data.
Host machine besides power supply to the hand-held probe, the host machine can also receive the measurement data transmitted from the hand-held probe, so as to perform display and storage, meanwhile, it can also realize the functions of alarm setting, storage mode setting and display mode setting, etc., the operation is simple and the using is convenient. When the concentration exceeds the alarm value, the detector shall issue alarm signal, prompting gas leakage, and reminding people of adopting measures early.
