Holiday Detector

A Preventive coating is applied to the surface from preventing corrosion. In coating a puncture may be due to manufacturing process or any other reason. The damage in this coating is called "HOLIDAY".

Detection

A material having proper coating is non conductive of electricity. Any puncture / bare portion leads to the current flow of electrical power. A high voltage is applied through moving electrode (Ring electrode / rubber brush) on coating material and a current jump is observed. If any current jump is observed, it is marked as HOLIDAY

UNIQUE TECHNICAL FEATURES

Its range of voltage from 8 KV to 30 KV in 12 steps, allows you to set the voltage exactly to the level you desire for the coating you are inspecting, any pipe size from 2" to 60" whatever the coating may be somatic, tar, asphalt extruded coats, tapes or thin film epoxy coating. You have at your control the voltage setting that you require. One batteries and a universal charger are part of the package. More efficient circuitry means reduced current drain and prolonged battery life and cost saving.
