Use a spark tester to test plastic welds, coatings, linings, and sealed surfaces for leaks, pinholes, and holiday defects. Run the spark tester along the weld or surface and if there is a hole or defect, a harmless spark will pass through the opening. The handheld high-frequency generator uses Tesla coil technology for fast, reliable leak detection.
