Ion Science TVOC Volatile Organic Compound Monitor

The Ion Science TVOC is a fixed continuous photoionization unit for the detection and measurement of total volatile organic compounds (VOCs) with one of three selectable ppm detection ranges. It uses advanced patented Fence Electrode technology, with increased resistance to humidity and contamination.

The TVOC uses a diffusive sample technique resulting in less contamination issues compared to pumped systems, reducing lamp cleaning and servicing requirements. Simple to install service and calibrate, TVOC requires no hot work permit and the PID sensor is accessible and changeable in a matter of seconds.
