HD-201C:0.5-35KV
4,Display:pointer
5,High voltage control system:Ordinary potentiometer adjustment
6,DC supply:12v
7,Consumption:＜5w
8,Alarm delay:1-2s
9,High voltage probe:Electronic high voltage generator
10,Packing:metal chest
11,Main dimension: 165mm×155mm×68mm
12,Weight:1.5kg(Including battery)
【Principle】
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.
【Test voltage schedule】
