TVOC, the fixed VOC gas detector from Ion Science

TVOC [fixed VOC gas detector]

TVOC is a fixed VOC gas detector, manufactured by Ion Science. The TVOC provides continuous detection and measurements within minutes.

The detector features the patented PID sensors and Fence Electrode Technology by Ion Science. The Fence Electrode Technology provides increased resistance to humidity and contamination.

The instrument has ATEX and IECEx approvals, which makes the device suitable for Zone 1 and Zone 2 hazardous areas. The robust TVOC is ideal to use in manufacturing and other industries.

The detector can be integrated with the DCS control system to provide warnings and to gain control over high VOC levels. The fixed VOC gas detector is easy to install, service and calibrate.
