Volatile Organic Compounds Fixed PID Detector

TVOC

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
