Functional characteristics

The electric spark detector is an instrument used to detect the quality of metal anti-corrosion coatings. This instrument can be used to perform quality testing on coatings of different thicknesses, such as glass lining, fiberglass, epoxy coal tar asphalt, and rubber lining. When there are quality issues with the anti-corrosion coating, such as pinholes, bubbles, and cracks, the instrument will emit a bright electric spark and sound an alarm.

The electric spark detector is powered by a nickel hydrogen battery (which has the advantages of high capacity, long service life, light weight, no pollution, no memory effect, and can quickly charge and discharge, making it an ideal green and environmentally friendly product suitable for outdoor operations).

This instrument is designed advanced and stable, and can be widely used in industries such as chemical, petroleum, rubber, enamel, etc. It is a tool used to test the quality of metal anti-corrosion coatings.

operational principle

Electric spark detector, also known as electric spark leak detector, electric spark leak detector, etc.

This instrument is mainly used to detect the presence of defects such as pinholes and sand holes in thick non-conductive coatings on metal substrates.

The electric spark detector is a device that applies a certain amount of pulse high voltage to the surface of the conductive substrate anti-corrosion layer. If the anti-corrosion layer is too thin, leaks metal or has gas leakage pinholes, when the pulse high voltage passes through, it forms an air gap breakdown and generates spark discharge. At the same time, it sends a pulse signal to the alarm circuit, causing the alarm to sound an alarm, thereby achieving the purpose of detecting the anti-corrosion layer.

Usage precautions

1. Before use, the operator should carefully read the instrument user manual, strictly follow the operating specifications, pay attention to protecting the instrument, prevent falling, touching, and high temperature, and do not place it near damp and corrosive gases.

2. When testing, it is necessary to choose an appropriate grounding point to ensure the quality of the test.

(1) The detection of anti-corrosion coating on the surface of small volume metal objects requires the object being tested to be supported by an insulator for more than 20cm, and then the grounding wire should be well connected to the metal object for detection.

(2) For the detection of large volume or flat objects, when there is good contact between the tested object and the ground, simply connect the grounding wire to the ground for testing.

3. During the testing process, the testing personnel should wear high-voltage insulation gloves, and no one should come into contact with the probe and the tested object to prevent electric shock!!!

4. The surface of the tested anti-corrosion layer should be kept dry. If there is conductive layer (dust) or clean water, it is difficult to determine the exact location of the leakage point.

5. When the instrument is not in use, make sure to turn the power switch to the "off" position!!!

6. When the undervoltage indicator light is on, please make sure to charge it in a timely manner!!!
