TVOC 2 Continuous VOC Gas Detector| Air-Met Scientific

Overview

The Ion Science TVOC 2 detects a large range of gases. This robust fixed Volatile Organic Compounds (VOCs) 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.

Seamless integration with DCS - 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.

IECEx Approved - The TVOC 2 fixed continuous VOC gas detector IECEx approvals which allow TVOC 2 to be used in Zone 1 hazardous areas with safety barriers.

Simple to Use- Simple to install, service and calibrate, the Ion Science 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.
