PHD-620 Pin hole detector
Pin Hole Detector
The PHD-620 Pin Hole Detector is used to test the integrity of a coated surface by identifying pin holes and flaws in the coating.
Pin holes or flaws in the coating may lead to premature failure of the coating – early identification allows for corrective action to be taken.

Product description
The PHD-620 Pin Hole Detector identifies pin holes and flaws in the coating by passing a selectable voltage of 9 volts, 67.5 volts, or 90 volts, through a wet sponge which is moved over the coated surface. The voltage will make a path through the wetting agent to the pin hole or flaw in the substrate, an audible alarm will sound and a red light will flash on the unit identifying the area for closer inspection. The application of the test is safe and does not cause burn marks or damage to the coating.
The PHD-620 Pin Hole Detector can be carried by the operator due to its light weight and portable design. The PHD-620 Pin Hole Detector is supplied in a hard plastic foam filled carry case complete with 150mm broad sponge assembly, and earthing cable.
A calibration certificate traceable to UKAS is available as a cost option upon request.
Complies with International Standards: BS EN ISO 8289 A, BS 7793-2, ASTM D-5162, ASTM G62-87, ASTM G6-83, NACE RP 0188
