MiniTest 70E Coating Thickness Gauge

The MiniTest 70E is a pocket sized, lightweight and handy coating thickness gauge in a pencil format with a built-in sensor designed for easy operation, this gauge is the ideal tool to measure any ferromagnetic substrates (e.g. steel) and also for non-ferromagnetic substrates (non-ferrous metals like aluminium, brass etc.). With user friendly features which allows users to select units of mils or microns. The spring-mounted sensors are equipped with wear-resistant sensor poles for measurements on rough and abrasive substrates.
Designed for measurement of insulating coatings such as paint, enamels, anodic films etc, on non-ferrous metal bases such as aluminium, copper, brass, etc and for  ferro-magnetic bases such as constructional steel, car bodies, etc.

Models Available

MiniTest 70E-FN – Combination Ferrous & Non-Ferrous Model

Measuring range 0 to 3 mm / 118 mils on steel substrates and 0 to 2.5 mm / 95 mils on non-ferrous metals.
