The MiniTest 70 is a pocket sized, versatile and accurate thickness gauge with built-in sensor. Especially designed for easy operation, this gauge is the ideal tool to measure any non-magnetic coatings on steel and/or any insulating layers on non-ferrous metals.
Coating thickness gauges designed for measurement on non-ferrous metals can measure insulating coatings such as paint, enamels, anodic films, etc, on non-ferrous metal bases such as aluminum, copper, brass, etc.
The spring-mounted sensors are equipped with wear-resistant sensor poles and ensure durability even when used for measurements on rough and abrasive substrates.
With coating thickness gauges designed for measurement on ferrous metals, non-magnetic coatings such as paint, enamels, chrome, etc., can be measured on ferromagnetic bases such as constructional steel, car bodies, etc.
The MiniTest 70 Series provides accurate, non-destructive coating measurements on steel and non-ferrous metals (FN model). Also, the FN model is equipped with a dual sensor for automatic identification of the substrate. According to the substrate, it adjusts to the appropriate measuring principle: magnetic induction or eddy currents principle.
Both models are provided with a quick statistics mode to calculate the number of readings, average, standard deviation and min./ max. value which makes the MiniTest 70 ideal for on-site operations.
