This spark tester offers a fast, reliable solution for detecting flaws, pinholes, and weld defects in non-conductive coatings, linings, and membranes on conductive substrates. Designed to inspect materials 1mm to 30 mm (0.04" to 1.18") thick, this unit is ideal for high-precision leak detection and checking butt-welded and overlap joints in industries such as plastic fabrication, petrochemicals, pipeline construction, and rubber manufacturing. Housed in a durable, lightweight aluminum case, the ST-AC Pro' features a compact benchtop design with an integrated folding handle/stand for convenient use in the lab or field. It delivers a pulsed ring high-frequency AC output, adjustable between 10 and 55 kV, and comes equipped with a 6” flexible probe and 6-1/2' test probe lead for reaching difficult or confined areas.
