The ST-AC Pro High Frequency Spark Tester provides a quick and effective means of inspecting thicker coatings and linings. Coating and material thicknesses of 0.040" to 1-3/16" (1mm to 30mm) can be tested.

It can be used for testing of welded joints in plastics & rubber, checking vacuum under glass, as well as for thicker coatings and linings in the petro-chemical and pipeline construction industries.

A flexible probe is included with the unit but additional insulated extension rods and electrodes can be supplied if required. However, to ensure the stability of the output voltage, large electrodes should not be used. The recommended maximum size is 6" (150mm).
