HUATEC HD-105 High voltage Pinhole Detector / Holiday Detector
Product introduction
HUATEC HD-105 High voltage Pinhole 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-105 use lithium battery for power source, it is also can be used
in field.
Battery can be replaced by customer themselves, useful for long
time testing work in field.
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.
Application
The equipment design of HD-105 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.
