About Coating Thickness Gauge – MiniTest 650

The MiniTest 650 is a rugged coating thickness gauge with a fixed external probe for all non-magnetic coatings on steel and all insulating coatings on non-ferrous metals.  The instrument is particularly suited to measure coating thickness in rough environments and on abrasive surfaces for example sandblasted steel, heavy duty corrosion protection in ship building, at offshore installations and mining facilities and also on plasma-sprayed surfaces.

The instrument is available in 3 model options: F, N and FN with fixed universal probe offering automatic substrate identification for quick measurements and is ideal for measuring coatings with a thickness of up to 2 and 3 mm.

Various Models Available:

MiniTest 650 F
