ElektroPhysik’s MiniTest 70 series pocket size coating thickness measurement gauge with SIDSP 32-bit-signal processing technology. The series will be available in two models, the MiniTest 70 F is intended for measuring non-magnetic coatings over ferrous substrates and the MiniTest 70 FN will additionally measure insulating coatings over non-ferrous metals. The measuring range on the ferrous model is 120 mils and the non-ferrous range is 100 mils. The accuracy statement is +
(.006 mils + 2% of the reading) following a two point setup. Gauge repeatability is +
(0.04 mils + 1% of the reading) . The minimum substrate thickness for ferrous applications is .020” thick and the non-ferrous substrate requirements are .0016” of material thickness.
Other features include user switchable measuring mode from mils to µm, user controlled auto switch off to conserve battery life, and a stats function that displays how many readings have been accumulated, the mean value, standard deviation as well as the high and low readings in the group.
