MiniTest 70 Coating Thickness Gauge

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 aluminium, 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.

2 Models Available
MiniTest 70F – Ferrous Only Model
MiniTest 70FN – Combination Ferrous & Non-Ferrous Model

(The FN model is equipped with a dual sensor for automatic identification of the substrate.)

The MiniTest 70 Series provides accurate, non-destructive coating measurements. 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.
