intelligence pulsed high voltage protecting coating quality detector holiday detector
1.1 What is HD-105A
HD-105A holiday detector is intelligence pulsed high voltage protecting coating quality detector. It install anti-jamming intelligent chip, anti-jamming LED screen and brand new digital control circuit to make a accurately high voltage output ±(0.1KV+3%reading).It can adjust its value of voltage according to the thickness of protecting coating. HD-105A use lithium battery for power source, it is also can be used in field.
1.2 Theory
When high voltage probe brushed pass non conductive coating, If the coating is too thin or metal has leakage or pinhole, the air gap will be punctured and produce spark discharge when pulse high voltage. At same time, detector will record leak number.
1.3 What it can be used on?
The equipment design of HD-105A is advanced, stable and reliable, which can be widely used in chemical industry, oil, rubber and enamel, so it is an essential tool used to detect metal anti-corrosion coating quality.
