PhoCheck+ PID Detector – Advanced, Humidity Resistant PID for VOCs

The PhoCheck+ photoionisation (PID) detector is a technologically advanced humidity resistant PID for volatile organic compounds (VOCs), providing rapid response and accurate detection. The PhoCheck+ PID detector has a dynamic range detecting VOCs from 1 ppb to 10,000 ppm.

Proven PID Technology

Independently verified as the best performing PID detector on the market, its unique patented Fence Electrode Technology incorporates a three-electrode format enabling proven resistance to humidity and contamination, giving optimal performance in the field.

Evidence shows the PID detection capabilities of the PhoCheck+ give faster, more accurate and more consistent results, outperforming all competition.

The PID Detector of Choice

With a dynamic detection range capable of detecting VOC’s at low toxicity thresholds and high explosive limits, PhoCheck+ is the PID detector of choice for industries including; environmental, petrochemical, HazMat and confined spaced entry.  Its accuracy and rapid response provide optimal performance in the field, giving you the results you can rely on.
