COATING THICKNESS GAUGE The 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. MiniTest 70 F With statistics display (number of readings taken, mean values, standard deviation, maximum, minimum). Suited only for ferromagnetic substrates (e.g. steel). Measuring range 0 to 3 mm / 118 mils. Enables 1-point and 2-point calibrations. MiniTest 70 FN With statistics display (number of readings taken, mean values, standard deviation, maximum, minimum). Suited for ferromagnetic substrates (e.g. steel) and also for non-ferromagnetic substrates (non-ferrous metals like aluminium, brass etc.). Measuring range 0 to 3 mm / 118 mils on steel substrates and 0 to 2.5 mm / 95 mils on non-ferrous metals. Enables 1-point and 2-point calibrations.
