The MiniTest 70B is a pocket sized, versatile and accurate thickness gauge with built-in sensor. It is a lightweight and handy coating thickness gauge in a pencil format with a 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. The spring-mounted sensors are equipped with wear-resistant sensor poles and ensure durability even when used for measurements on rough and abrasive substrates.
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 aluminium, copper, brass, etc.
And for measurement on ferrous metals, non-magnetic coatings such as paint, enamels, chrome, etc., can be measured on ferro-magnetic bases such as constructional steel, car bodies, etc.
The MiniTest 70B Series provides accurate, non-destructive coating measurements on steel and non-ferrous metals. 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.
Measuring range 0 to 3 mm on steel substrates and 0 to 2.5 mm on non-ferrous metals.
