Pin hole detector ElektroPhysik
PoroTest

Holiday detector for detecting pores and holes in insulating materials on conductive substrates such as steel, aluminium, etc. Typical applications are: Linings and coatings applied on ducts, pipes, hulls, oil and storage tanks, enamel, paint, rubber and bitumen linings, vessels and tanks, GFK and other plastics materials. Tanks or vessels must be filled with water or other conductive material.
Portable and storage battery supplied, PoroTest 7 offers a great variety of electrodes.

Test voltages:
0.5..7 kV for testing materials from 0.03..1.7 mm thickness
6..11.3 kV for testings materials from 1.4 .. 11.3 mm thickness

Now with elctronic control of test voltage depending on material thickness and vice versa!
