Volatile Organic Compounds


Fixed PID Detector for Continuous VOC Detection

TVOC is a fixed photoionisation detector (PID) designed for continuous measurement of total volatile organic compounds (VOCs). New ATEX approvals enable a 3 wire TVOC system to be used in Zone 2 hazardous areas, without safety barriers. ATEX and IECEx approvals allow TVOC to be used in Zone 1 hazardous areas, with safety barriers.

  • Independently verified as best performing PID technology
  • Patented Fence Electrode Technology for fast, accurate humidity resistant operation
  • ATEX: Zone 2 hazardous areas without safety barriers (3 wire option)
  • ATEX & IECEx: Zone 1 hazardous areas with safety barriers (4 wire option)
  • 3 wire option allows direct replacement of an existing PID area monitor (Zone 2 ATEX)
  • Selectable detection range of 0 - 10 ppm, 0 - 100 ppm or 0 - 1000 ppm
  • Diffusive monitoring - no pump required
  • Scaled 4-20 mA analogue output
  • Includes a 10.6 eV lamp
  • Easy access PID sensor allows simple servicing
  • Simple calibration procedure

GMA 200-MT Controller

  • A variety of trnsmitters can be connected for measurement of combustible, toxic gases/vapors and oxygen
  • Multiple relay configuration
  • Flexible, reliable and economic
  • Intuitive, backlit graphical LCD with "traffic light funcion" (green, amber, red)
  • SIL certification
  • DIN rail mounting or wall mounting
