PTM600-AQI portable gas detector can be selected to detect 1~16 factors (including gas concentration, temperature and humidity, particulate matter, differential pressure, wind speed, etc.) simultaneously.


PTM600-AQI2 Air Quality Monitoring System 

PTM600-AQI2 portable gas detector  can be selected to detect 1~16 factors (including gas concentration, temperature and humidity, particulate matter, differential pressure, wind speed, etc.) simultaneously.


* Up to 30 kinds of factors can be detected at the same time; the specific detection type depends on the internal sensor configuration of the instrument

* Units are freely switchable, units can be selected: ppm, mg/m3, ug/m3, VOL%, LEL%, pphm, ppb, mg/L.
* Built-in pump suction measurement, sampling distance greater than 10 meters; support real-time detection or timed detection (turn off the air pump when not detecting)
* Rich man-machine interface: 3.5-inch high-definition color screen display, the menu interface uses high-definition simulation graphics to display the function name of each menu.
* High-capacity data storage function, support a variety of storage methods.
* A variety of communication interfaces, optional printing function.
* Three display modes can be switched: Six gas concentrations are displayed at the same time (more than six interfaces are displayed cyclically), single-channel gas concentrations are displayed cyclically, and real-time curves are displayed.
* Data recovery function Partial or full recovery can be selected, eliminating the worries caused by misoperation.
* Can set whether to display the maximum value, minimum value, average value 
* A variety of alarm modes alarm mode setting, alarm status indication in multiple directions when the alarm:
     → Alarm mode: sound and light alarm, visual alarm, sound and light + visual alarm.
     → Alarm types: concentration alarm, undervoltage alarm, fault alarm
     → Alarm mode: low alarm, high alarm, interval alarm, weighted average alarm
* Misoperation identification function Concentration calibration misoperation is automatically identified and stopped, which can avoid the bad caused by human factors.
* Zero point automatic tracking Long-term use is not affected by zero point drift
* Multi-stage calibration of target point Ensures linearity and accuracy of measurement, and can comply with both national standards and local metrology bureau standards.
* Intrinsically safe circuit design Explosion-proof, shock-proof, anti-static, anti-electromagnetic interference, through the national standard test
* Protection level up to IP66 splash-proof, dust-proof, explosion-proof, shock-proof
