 The detector generates a high DC voltage that is applied to the coating surface through a probe. The detector is connected to the substrate via the high voltage returned. When the probe is passed over a coating flaw, then the electrical circuit is completed and current flows from the probe to the substrate. As a result, audible and visual alarms are activated in the detector and a spark may be produced at the flaw. 


Standard configuration: The brush plate 
Optional configuration: The fan-shaped brush, The inner circular brush,the exterior circular brush
