TVOC the Worlds First Intrinsically Safe Fixed PID Gas Detector

Ion Science’s TVOC is a fixed continuous monitor for the detection and measurement of total volatile organic compounds (VOCs). It is ideal for use in manufacturing and process industries where VOCs are typically present. With a 420 mA analogue output TVOC can be simply integrated into a DCS control system to give warning or control of high VOC levels in the working environment.

TVOC has been designed to be simple to install, service and calibrate. TVOC is the first fixed photoionisation detector (PID) that is ATEX approved. Being intrinsically safe means there is no need for an expensive explosion proof enclosure. It also allows for simple servicing with no hot work permit and the PID sensor is accessible and changeable in a matter of seconds. TVOC also benefits from using a diffusive sample technique which results in less contamination issues, compared to pumped systems, reducing lamp cleaning and servicing requirements.
