The MiniTest 70 enables non-destructive measurement of non-magnetic coatings (paint, synthetic material, chrome, etc.) on a ferromagnetic substrate (steel) and insulating coatings (lacquer, enamel, synthetic material, etc.) on conductive substrates (aluminium, copper, austenitic stainless steel).

The spring-mounted sensors are equipped with wear-resistant sensor poles to give especially high durability also when measuring abrasive substrates.
