The Holitech DC Holiday Detector tests and detects pinholes and flaws in insulated coatings on conductive substrates.
Operation is by a test voltage being applied to the coating by moving a brush electrode across the surface and where there is either a pinhole or flaw, the voltage will spark through the coating, a red indicator will flash and an audible alarm will sound. The detected flaw can be marked for subsequent repair, and testing resumed for the remaining surface area.
The Holitech is a compact and lightweight instrument, which can easily be carried by the operator with the supplied Neck Strap.
The test voltage is high impedance, allowing for safe testing, and does not damage or cause burn marks to the coating. Coatings on concrete as well as steel and iron substrates can be tested.
Calibration Certificates are available with traceability to UKAS.
