- Model EQMS-200 - Vocs Online Monitoring System



EQMS-200 VOCs online monitoring system adopts PID (photoionization detector ) for gas detection. The target gas is irradiated/bombarded by ultraviolet light produced by the ion lamp, and is ionized after absorbing enough uv energy. The concentration of the target gas can be detected by detecting the tiny current generated after the ionization of the gas.

  • 4.3-inch LCD screen, good human-computer interaction experience .
  • IP65 high standard protection design, which can be installed directly in the paint shop and outdoors .
  • Automatic zeroing and automatic calibration design greatly reduce maintenance workload .
  • Modular design, low maintenance cost.
  • Automatic temperature and pressure compensation can accurately calculate the gas concentration under normal pressure .
  • Battery module can be matched for continuous monitoring in power failure state .
  • Scalable SD memory card design with unlimited storage of historical data .
  • The alarm signal will be output to avoid invalid data if the sampling port is abnormally blocked
