TVOC 2 Fixed VOC Gas Detector
ION
TVOC 2 Fixed VOC Gas Detector
The total VOC gas detector has a selectable detection range of 0 – 10 ppm, 0 – 100 ppm or 0 – 1000 ppm and is suitable for use in manufacturing and process industries where VOCs are commonly found. With its 4-20 mA analog output, the fixed continuous VOC gas detector can be easily integrated into a Distributed Control System (DCS) to provide alerts to elevated VOC levels and maintain control in your work environment.
The TVOC 2 gas detector has ATEX approvals, which allow it to be used in Zone 2 hazardous areas with a 3-wire connection without the need for a safety barrier. Thanks to ATEX and IECEx approvals, the TVOC 2 gas detector can be used with a safety barrier in Zone 1 hazardous areas.
