Description

The Elektrophysik MiniTest 70 is a lightweight and handy coating thickness gauge (DFT gauge) in a pencil format with a built-in sensor. It enables non destructive measurement of

  • non-magnetic coatings (paint, synthetic materials, chromium etc.) on a ferromagnetic substrate (steel)
  • insulating coatings (varnish, enamel, synthetic material etc.) on conductive substrates (aluminium, copper, austenitic stainless steel) (only in the FN type models)

The spring-mounted sensors are equipped with wear-resistant sensor poles and ensure durability even when used for measurements on rough and abrasive substrates.
