Versatile coating thickness gauges
• for fast and precise measurements of – non-magnetic coatings on steel 0 … 3,000 μm
– insulating coatings on non-ferrous metals 0 … 2,500 μm
• automatic identification of the substrate material
• built-in sensor
• proven measuring methods
• statistics function
Application Designed for quick and easy nondestructive coating thickness measurement, the MiniTest 70 series is available in two models: MiniTest 70 F with built-in sensor for measuring non-magnetic coatings applied on steel MiniTest 70 FN with a builtin dual sensor for measuring nonmagnetic coatings applied on steel and insulating coatings on non-ferrous metals. MiniTest 70 – Pocket-sized Coating Thickness Gauge Description The MiniTest 70 Series are compact, pocket sized coating thickness testing gauges. The simple 4-button operation, clear display and built-in statistics displaying the number of readings taken, the minimum, maximum, mean values and standard deviation makes the MiniTest 70 Series ideal for on-site applications. With new simplified operation, no special training is required to operate these gauges. An audible signal confirms reading acquisition. The MiniTest 70 Series are powered by a standard single AA battery and when the battery gets low, a BAT symbol appears to indicate that the battery needs to be changed. Special feature of the MiniTest 70 FN model: It incorporates a dual sensor for automatic identification of the substrate material. The gauge upon contact with the surface automatically switches to the suitable measuring principle based on your application: magnetic-induction or eddy currents.
