AC Spark Tester

When selecting an AC spark tester, factors such as the thickness and conductivity of the material being tested should be considered to match the appropriate output voltage range. The detection speed determines the model: manual types are suitable for small parts, while automatic types are better suited for production lines. The electrode shape should be chosen based on the flatness of the material: curved electrodes are used for curved surfaces, and flat plate electrodes are used for flat surfaces. Environmental humidity affects sensitivity; standard models are suitable for regular workshops, while enhanced protection versions are recommended for high-humidity environments.
