Product Description

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.


Main applications for holiday detector

1,Oil & gas anticorrosive factory, pipelining company, construction departments and qualitative inspect branch.
2,Use to gas company and water company pipeline inspecting
3,Use to shipbuilding, petrochemical plant, factory, machinery plant, enamel factory and bridge engineering anticorrosion-layer inspecting.
4,Can be used for pipeline transportation company anticorrosion-layer inspecting


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!!
