The GDA 2000VOC is an explosion proof (IEC Ex) certified VOC gas detector using PID technology as means of detection.

Locally Technically Supported by Gas Detection Australia

IECEx Approved

The sensor is powered from 24V and gives 4-20mA output.The measruing range of gas varies from 5ppb ~ 300ppm dependent on gas being detected.

  • Continuous detection of VOC gas in explosion hazardous area with flame proof structure
  • Self diagnosis function with built-in Microprocessor
  • Low concentration VOC gas detection by PID sensor
  • Stable quality and proved detection principle for service life
  • Multi functions and high quality with low cost of ownership
  • Built-in back light LCD or OLED display
  • Easy Configuration of monitoring by HART communication
  • Auto calibration and program setting with a magnet bar
  • 4-20mA DC output signal
  • 3-wire connection for signal & power
  • Calibration and maintenance by one-man
