The PhoCheck Tiger VOC detector is a revolutionary handheld PID instrument for rapid, accurate detection of volatile organic compounds (VOCs). Its photoionization detection (PID) capabilities utilize advanced patented Fence Electrode technology, a three-electrode format with increased resistance to humidity and contamination. A robust handheld VOC detector, the PhoCheck Tiger provides a dynamic detection range of one parts per billion (ppb) to 20,000 parts per million (ppm), offering the widest measurement range of any other VOC detector on the market.
