HOD-600 DC holiday tester
DC Holiday Tester
The HOD-600 Holiday Tester 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.

Features
The HOD-600 Holiday Tester identifies pin holes and flaws in the coating by passing a voltage through a brush electrode which is moved over the coated surface – the voltage will spark through a pin hole or flaw to the substrate identifying the area for closer inspection. Upon identification of a pin hole or flaw an audible alarm will sound and a red indicator will flash on the unit. The application of the test is safe and does not cause burn marks or damage to the coating due to the test voltage being of high impedance.
The HOD-600 Holiday Tester can be carried by the operator using the neck strap provided due to its light weight and portable design. The HOD-600 Holiday Tester is supplied in a hard plastic foam filled carry case complete with high voltage probe, brush electrode, earthing cable, and neck strap.
