TVOC 2 Continuous VOC Gas Detector
This robust fixed continuous VOC gas detector 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. 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 detector requires no hot work permit and the PID sensor is accessible and changeable in a matter of seconds. Key Features : PID independently verified as best performing on the market In-built humidity resistance with no need to compensate Anti-contamination design for extended field operation Accurate continuous over all environmental conditions Rugged and robust design withstands harsh environments Large LCD display for clear readings ATEX and IECEx approved Simple to use – minimal training required Easy access PID sensor for fast, simple servicing Simple calibration procedure Easily integrated into a control system |
