Total VOC Detector for Continuous Volatile Organic Compound Monitoring

TVOC is a fixed continuous VOC detector for the detection and measurement of total volatile organic compounds (VOCs). Its photoionisation detection (PID) capabilities utilise advanced patented Fence Electrode technology, a 3 electrode format with increased resistance to humidity and contamination.

A robust fixed VOC detector, TVOC has a selectable detection range of 0 – 10 ppm, 0 – 100 ppm or 0 – 1000 ppm and is ideal for use in manufacturing and process industries where VOCs are typically present.

With a 4-20 mA analogue output, the TVOC VOC detector can be simply integrated into a DCS control system to provide warnings and enable control of high VOC levels in the working environment.

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.

The TVOC fixed VOC detector utilises a diffusive sample technique resulting in less contamination issues compared to pumped systems, reducing lamp cleaning and servicing requirements. Simple to install service and calibrate, TVOC requires no hot work permit and the PID sensor is accessible and changeable in a matter of seconds.

The TVOC fixed VOC detector is also available for use with a pumped system for applications where sample conditioning is required.

TVOC is part of a range of VOC detectors that includes the hand held PhoCheck Tiger, PhoCheck+ and FirstCheck+ instruments.
