This robust fixed continuous VOC gas monitor 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 fixed continuous VOC gas detector can be simply integrated into a Distributed Control System (DCS) to provide warnings and enable control of high VOC levels in your working environment.
Features
The TVOC 2 fixed continuous VOC gas detector has ATEX approvals that 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 fixed continuous VOC gas monitor requires no hot work permit and the PID sensor is accessible and changeable in a matter of seconds.
Other fixed gas detectors include: Titan, Falco Diffused and Falco Pumped.
