Coating Thickness Gauges MiniTest 70

The MiniTest 70 is a lightweight and handy Coating Thickness Gauges (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.

Application

Non destructive measurement of:

Non-magnetic coatings like varnishes, enamels, chromium and zinc on ferromagnetic base materials (e.g. steel)
Insulating coatings like varnishes and anodic coatings on non-ferrous metals (e.g. aluminium, copper, austenitic stainless steel, brass)

Features

Accurate coating measurement of up to 3mm(F range) and 2.5 mm(N range)
Dual sensor for automatic substrate identification and setting the suitable measuring principle: eddy currents or magnetic induction (not in model F))
Wear-resistant probes with long service life
Lightweight: only 80 grams
Dual sensor for automatic identification of the substrate (FN model). According to the substrate, it adjusts to the appropriate measuring principle: magnetic induction or eddy currents principle.
Quick statistics mode to calculate the number of readings, average, standard deviation and min., max. value
lightweight: 80 grams / 2.8 oz only
