AC&DC Intelligent Frequency Conversion Anticorrosive Coating High Voltage Holiday Test Equipment
Two model: 0.5KV-7KV (HD-109A) 6KV-35KV (HD-109B)
Spark detector, also known as spark leak detector, spark leak detector, etc. The instrument is mainly used to detect whether there are pinholes, trachoma and other defects on the thick non-conductive matrix of metal substrate. The instrument is very simple to use, one end grounding, the other end is the probe, (probe form many carbon brush type, circle spring type, flat rubber type), the instrument through the high voltage probe out of DC high voltage, when the probe through the defect of the coating surface, the instrument will automatically sound and light alarm.
Check the instrument before use, the instrument brush must not touch the human body, so as not to cause injury.
Main applications for spark detector
1,Oil and gas anticorrosive production factory, pipeline production company, construction departments and qualitative inspect branch.
2,Using for gas or oil company and water company pipeline inspecting
3,Using for factory of ship-building, petrochemical plant, machinery plant, enamel factory and bridge engineering anticorrosion-layer inspecting.
4,Widely used for pipeline transportation company anticorrosion-layer inspecting
General information:
HUATEC 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.

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!!
