Spark Tester SWT-NS004

The spark tester applies current to the surface of the welding joint. When there is a leak at the joint, the device will send out an obvious alarm signal. Used to detect holes in geomembranes, especially in smaller areas. When used, spark discharges are generated when contact is made with the conductive path, indicating that the integrity of the geomembrane is compromised.

Application

After welding: Leak detection

The welding quality of geomembrane is the key to ensure its waterproof function, especially in anti-seepage projects. Spark tester can help identify whether there are leaks in the welding joints. During the welding process, if the welding is not firm or there are defects such as bubbles and cracks, it may cause moisture penetration and affect the quality of the project.

Spark Tester FAQ

What Is a Spark Tester?

A spark tester is a device used to detect insulation defects in wires, cables, and coatings by applying high voltage and checking for sparks.

How Does a Spark Tester Work?

It generates a high-voltage field around the test object, and if insulation is faulty, sparks will jump through the defect, indicating a failure.

Where Is a Spark Tester Used?

It is commonly used in wire and cable manufacturing, pipeline coating inspections, and quality control processes.

What Are the Types of Spark Testers?

The main types include high-frequency AC spark testeWhat Is a Spark Tester.

How to Ensure Accurate Spark Tester Results?

Proper calibration, maintaining the correct voltage settings, and ensuring clean test surfaces help achieve reliable and accurate results.
