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 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: 1Display screen of host machine 2 Host machine 3 Power switch 4Aviation plug 5Filter cap 6Probe rod 7Probe panel 8Probe 9Communication 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. 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 angleThe host machine adopts 3.5 inch color touch display screen, the brightness is high, the visual angle is small and the contrast is adjustableThe sensitivity is high, the detection of leakage can reach 0.1 ppm, and the precision can reach 1ppm at mostGood stabilitySwift response timeAcoustoptic alarmFacilitates carryingIt can realize manual storage of measurement data;Long service life of sensorTechnical parameters Measurement principleInfrared (NDIR)Measurement rangeRefer to lectotype tableSampling modePumping typeService temperature-10 60°CPower supply7.2V DC, internal battery power supplyResponse time (T90s)1 5 second(s)Warm-up time100 secondsProbe unit rod length22cmService life of sensor>10 yearsCalibration timeCalibration once every six monthsAlarm modeBuzzer Executed standard GB12358-2006 "Gas monitors and alarms for workplace—General technical requirements"
