Portable 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 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.

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

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
