The TVOC 2 is a powerful, fixed continuous VOC gas monitor that incorporates a selectable detection range of 0–10 ppm, 0–100 ppm or 0–1000 ppm and is optimized for application in manufacturing and process industries where VOCs are normally present.
With a 4-20 mA analog output, the fixed continuous VOC gas detector can be easily incorporated into a Distributed Control System (DCS) to manage high VOC levels in your working environment and enable early warnings if necessary.
The TVOC 2 fixed continuous VOC gas detector features ATEX approvals that facilitate the use of a 3 wire TVOC system in Zone 2 hazardous areas lacking safety barriers, while its ATEX and IECEx approvals enable the use of the TVOC 2 in Zone 1 hazardous areas with safety barriers.
The TVOC 2 fixed continuous VOC gas monitor is easy to install, service, and calibrate and includes a PID sensor that is accessible and changeable in just a few seconds – it does not require a hot work permit.
Other fixed gas detectors include Falco Diffused, Falco Pumped and Titan.
