AC&DC Keypad Intelligent Frequency Conversion High Voltage
Holiday Test Equipment
Spark detector can be divided into DC spark detector and AC spark
detector for different purposes and use of the region. Dc spark
detector is mainly suitable for field construction, easy to use and
other open sites. Mainly powered by batteries. Ac spark detector is
mainly suitable for use in factories, workshops and other closed
places where power supply is convenient. Mainly through 220v power
supply. According to the different classification of electric spark
detector, users can choose the appropriate instrument according to
the different user site.

General introduction:
HD-108A/B/C series 110/230V AC/DC intelligent frequency conversion
electric spark pinhole holiday detector uses intelligent frequency
conversion high voltage detection technology, used to detect
pinholes, cracks and other damage and defects in non-conductive
coating on conductive substrate (such as metal), can be used to
detect the quality of insulating and anticorrosive coating on the
surface of storage tanks, valves and pipelines. Host for portable,
rugged ABS shell, the instrument appearance design is advanced,
stable and reliable performance, can be widely used in
anticorrosive engineering, plastic airtight joint detection,
concrete coating layer air tightness test, petrochemical pipeline
corrosion inspection, enamel production industries, is used to
detect an essential tool for metal surface insulating anticorrosive
coating quality.

Detection principle:
Spark detector is based on a variety of conductive insulating
coating on substrate surface to add a certain amount of pulse
pressure, such as anti-corrosion layer, thin metal or pinhole of
leak leakage, when pulse high voltage, air gap will be punctured
and produce spark discharge, at the same time send pulse signal to
alarm circuit, the alarm sound and light alarm, so as to achieve
the aim of the anticorrosive layer of quality testing.
Notice for operation:
1. Before use, the operator should read the instrument instruction
carefully, strictly follow the operation specifications, pay
attention to the protection of the instrument, prevent fall,
collision and high temperature, do not place near the humidity and
corrosive gas.
2. Select a proper ground point to ensure test quality.
(1) small volume of metal surface anti-corrosion layer detection,
to be detected by the object with insulation support more than
20cm, and then the grounding wire is well connected to the metal
object detection.
(2) For the detection of large volume or flat objects, when the
measured object has good contact with the earth, only the grounding
wire access to the earth can be tested.
3. During testing, testing personnel should wear high-voltage
insulating gloves, and no one should touch the probe and the object
under test, in case of electric shock!!
4. The surface of the tested anticorrosion layer should be kept
dry. If there is conductive layer (dust) or water, it is not easy
to determine the exact location of the leak point.
5. Power switch must be turned off when the instrument is not in
use!!
6. When the undervoltage indicator lights up, please be sure to
charge in time!!
Stable output voltage of high voltage gun!!
