The Holitech is a DC Holiday Tester, (Holiday Detector, Pinhole Tester, Spark Tester, Jeep Tester) which will test 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.

Range: 0 to 15kV / 0 to 30kV

The premature corrosion of a substrate is often due to the failure of it's coating. Major causes of failure are flaws in the finished coating, these include pinholes, holidays, inclusions, thin spots and bubbles.

The Elcometer 236's convenient carrying case allows the probe handle and accessories to be attached to the front making the Elcometer 236 ideal for field, site or laboratory inspection.

The Elcometer 266 has been specifically designed to revolutionise high voltage DC testing of coatings by making it safer, easier and more reliable than previously possible.
