The Unique spark tester PST100 to quickly test welds for watertightness. Thicknesses between 3mm and 30mm can be tested with this spark tester.

With the help of the high-frequency tester PST100, you can quickly and safely determine whether welds; receptacles, lacquer layers and / or the processed layers are closed. Thanks to the contactless spark generation, the device is maintenance-free, constant and ready for frequent use. The built-in stabilizing circuit allows the device to operate independently of fluctuations in the mains voltage.

Delivery with flexible probe (test pin) of 150mm long in a case.
The Buckleys spark tester is provided with a CE mark!


A “GAP TESTER” is available from Buckleys to adjust the spark. It is never actually sold, because the users adjust the spark tester themselves as follows:

The output voltage of the PST100 can be roughly set by dividing the test voltage by 1700, the answer is in mm. For example 20,000 Volt / 1700 = 11.76 mm. The test probe should be kept at the calculated distance from a piece of grounded metal and the output voltage will be increased until the spark pops the gap.
