HUATEC New HD-109A/B series electric spark detector



HD-109A/B series intelligent frequency conversion electric spark pinhole 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.


1. The special metal hose protects the connecting cable between the main engine and the high voltage generator;

2. Military-grade gold-plated connector to ensure the reliability of the connection;

3. Unique design, ABS case, beautiful, durable;

4. Light touch waterproof film keyboard, easy to operate;

5. AC/DC power supply can be switched quickly and automatically, AC/DC dual-use;

6. Large capacity lithium ion battery pack, energy saving and environmental protection;

7. Independent high pressure button, maximum protection of detection personnel safety, in line with international safety standards;

8. Intelligent frequency conversion high voltage detection technology is suitable for humid environment, the detection process does not generate static electricity;

9. Can be detected by dew wet or muddy and slightly conductive surface;

10. Can automatically identify different working probe (high pressure gun), self-calibration;

11. Digital display battery voltage and output high voltage;

12. When pinhole and other defects are detected, acousto-optic alarm;

13. The output high voltage can be accurately adjusted, and the display precision is high.

14. With overload protection function;

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.
