TVOC 2 fixed PID Detector
For continuous VOC monitoring
TVOC 2 is a fixed continuous PID detector for the detection and measurement of total volatile organic compounds (TVOCs). Its photoionisation detection (PID) sensor capabilities utilise advanced patented Fence Electrode Technology with increased resistance to humidity and contamination.
A robust fixed PID detector, TVOC 2 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, TVOC 2 can be simply integrated into a Distributed Control System (DCS) to provide warnings and enable control of high VOC levels in the working environment.
The instrument’s ATEX approvals enable a 3 wire TVOC system to be used in Zone 2 hazardous areas without safety barriers, whilst its ATEX and IECEx approvals allow TVOC 2 to be used in Zone 1 hazardous areas with safety barriers.
Simple to install service and calibrate, TVOC 2 requires no hot work permit and the PID sensor is accessible and changeable in a matter of seconds.
