Volatile Organic Compounds
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
TVOC 2
FIXED PID MONITOR FOR VOLATILE ORGANIC COMPOUNDS.
TVOC 2 is a fixed photoionisation
detector (PID) for the continuous
measurement of total volatile
organic compounds (VOCs).
TVOC 2 can accurately measure
three detection ranges.
TVOC 2 continually measures and
updates the output every second.
TVOC 2 utilises a diffusive
sample technique resulting in less
contamination issues compared
to pumped systems, reducing
lamp cleaning and servicing
requirements. The 4-20 mA
analogue output enables TVOC
to be integrated into a DCS
control system to give warning
or control of high VOC levels
in the working environment.
