TVOC 2 is a fixed photoionisation detector (PID) for the continuous measurement of total volatile organic compounds (VOCs). TVOC 2 can accurately measure three detection ranges. TVOC 2 continually measures and updates the output every second.

TVOC 2 utilizes a diffusive sample technique resulting in less contamination issues compared to pumped systems, reducing lamp cleaning and servicing requirements. The 4-20 mA analogue output enables TVOC to be integrated into a DCS control system to give warning or control of high VOC levels in the working environment. ATEX approvals enable a 3 wire TVOC system to be used in Zone 2 hazardous areas, without safety barriers.

Safety

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 requires no hot work permit and the PID sensor is accessible and changeable in a matter of seconds.
