DJ 6A Spark Leakage Holiday Detector for Anti Corrosion Coating Metal

Description

This detector can detect different thickness of coatings, such as glass lining, glass reinforced plastic, epoxy coal tar, rubber lining and so on. the detector will emit bright sparks and with sound alarm when something is wrong with the coating, such as the emergence of pinhole, air bubbles, cracks and cracks.

The detector is the essential tool used for detecting the quality of metal anti-corrosion coating and can be used in many industries including chemical, petroleum, rubber and ceramic, due to its sophisticated design and stable & reliable performances.

The Detector is mainly used to detect the presence of pinholes, blisters and other defects in thick non-conductive coating on metal substrates. The electric spark leak detector is very simple to use, one is grounded and the other is a probe. 

(There are many types of probes in the form of carbon brushes, circle springs, and flat rubber.) The electric spark leak detector sends DC high voltage through the high voltage probe. When the probe passes the defective coating surface, the EDM leak detector will automatically sound and light alarm.
