Holitech DC Holiday Tester

The Holitech is a Holiday Tester, (Holiday Detector, Holiday Test, Pinhole Tester, Spark Tester, Jeep Tester) which will test for Holidays and detect pinholes and flaws in insulated coatings on conductive substrates.

Where coatings have to provide an effective safeguard against corrosion, it is essential that any pinhole or flaws which will eventually lead to corrosion are detected using a Holiday Tester at the earliest possible stage, preferably immediately after the coating application.

The Holitech Holiday Tester applies a test voltage to the coating by moving a brush probe across the surface and where there is either a pinhole or flaw, the voltage will spark through the coating at the flawed location, a red flashing indicator on the Holitech Holiday Tester will flash and an audible alarm will sound. The detected flaw can now be marked for subsequent repair and testing resumed for the remaining surface area. If no flaws are detected the test will therefore be non-destructive.

The value of the test voltage for the Holitech Holiday Tester is determined by the dielectric or voltage strength of the coating thickness. As a rough guide the test voltage can be approximated between 3 to 5 volts per micron of coating thickness, therefore 1000 micron (1mm) would be approx 3kV to 5kV test voltage.

The Holitech Holiday Tester conforms to ISO 2746, ASTM G2-B, ASTM D4787, ASTM G6, NACE RP0188-88, JIS-G3491, JIS G3492, and AS 3894.1 specifications.

Calibration Certificates are available with traceability to UKAS.

Accurate voltage setting on the Holitech Holiday Tester is achieved by adjusting a 10 ten turn fine adjustment front panel control and the exact test voltage is displayed on a digital display with an accuracy of ±1%.

The Holitech Holiday Tester has an automatic fault detection feature installed which ensures that faults are detected at any voltage setting.

The Holitech Holiday Tester is ultra lightweight and possible the lightest Holiday Tester currently on the market, overall weight including batteries with handle is approx 1.6kg.

The test voltage is of low power and does not damage or cause burn marks on the coating.

When using the Holitech Holiday Tester, there are a number of important safety features built in. The test voltage is high impedance and drops to zero when a fault is detected, earth cable is lockable to prevent accidental disconnection. There is a probe discharge path incorporated to prevent any static charge being maintained.

Coatings on concrete as well as steel and iron substrates can be tested using the Holitech Holiday Tester

The Holitech is supplied in a Carrying Case complete with High Voltage Probe Handle, Band Brush Probe, Neck Strap, Earth Cable and Batteries fitted.
