Product Description

PTM350 Aerosol photometer



The online monitoring and pretreatment system is applied to 24-hour continuous online monitoring of on-site gas concentration. It is equipped with a 7-inch high-definition color screen to display on-site concentration, over standard on-site audible and visual alarm (optional), remote signal GPRS, DTU, Lora, and another transmission. The gas sensor of an internationally famous brand is adopted. The main detection principles include gas sensors based on the principles of electrochemistry, infrared, catalytic combustion, thermal conductivity, PID photo ion, etc.


  • Optional 1-6 kinds of compound gas detectors
  • The concentration display unit can be switched freely
  • A variety of communication methods are available 
  • Real-time monitoring via wired or wireless remote transmission, network transmission; 3-wire 4-20mA standard signal and standard bus RS485 (Modbus-RTU) output at the same time; optional frequency output 200-1000Hz, Hart protocol signal, 1-5V output, 2-wire 4-20mA, SMS alarm, wireless transmission (2-5km or unlimited distance); compatible with secondary instruments, data acquisition modules, PLC, DCS system, can drive related equipment.
  • Standard infrared remote control, through the infrared remote control function keys, can be a one-touch operation, can realize on dangerous occasions without opening the cover operation, such as: modifying the alarm point, concentration calibration, zero calibration, silence, restore factory, and other functions.
  • Rich human-machine interface
  • 1.7" HD color screen, display real-time concentration, alarm status.
  • High-temperature gas detection (optional)
  • Optional high temperature and high humidity pre-treatment systems can detect high-temperature flue gas.
  • Data recovery function, you can select partial or full recovery in case of misoperation
  • The maximum value and minimum value can be set to be displayed or not

  • Include 2 groups of relay switch output, sound and light alarm (optional), display visual alarm.
  • Alarm types include concentration alarm, fault alarm.
  • Multiple alarm mode settings: low alarm, high alarm, interval alarm, weighted average alarm
  • Misoperation identification function: concentration calibration misoperation is automatically identified and prevented to avoid bad human factors
  • Zero-point automatic tracking, long-term use is not affected by zero-point drift
  • Multi-stage calibration of target point to ensure linearity and accuracy of measurement
  • Chinese or English interface can be selected
  • Wide working temperature: -40~+70℃, support temperature compensation
  • Record calibration log, maintenance log, fault record, troubleshooting countermeasures, sensor life expiration reminder, next concentration calibration time reminder function.
  • Intrinsically safe circuit design, explosion-proof, with secondary lightning protection and anti-static capability. Meet national standards and resist high-intensity pulse surge current impact. With anti-reverse connection function. Meets EMI, EMC standards.
