The MiniTest 2500 and 4500 are high precision coating thickness gauges compatible with a large range of probes for measuring coatings on ferrous and non-ferrous metals. Different calibration methods and evaluation options for a wide range of tasks in the field of coating measurements.

MiniTest coating thickness gauges are not only useful in the laboratory but are equally qualified for use in industrial applications thanks to their rugged housing with a IP 65 rating. Both models feature USB output for connection to notebooks and PCs. The MiniTest 4500 additionally offers a Bluetooth output for wireless data transfer to mobile devices like Smartphones and printers directly on site. All gauge functions can be triggered directly pressing a single key of the illuminated keypad. The large display with background illumination adds to a high level of user comfort and ergonomics. A broad selection of measuring sensors is available for the MiniTest 2500/4500 line of coating thickness gauges allowing it to handle standard applications as well more complex measuring tasks.

The scope of application is determined by the sensor connected to the gauge:

F-type (ferrous) sensors work according to the magnetic induction principle and can measure non-magnetic coatings such as paint, enamel, rubber, aluminum, chrome, copper, zinc etc applied on iron and steel (including steel alloys and hardened magnetic steels).

N-type (non-ferrous) sensors work according to the eddy current principle and measure insulating coatings such as paint, anodizing, ceramics etc. applied on all non-ferrous metals (for example aluminum, copper, zinc die cast, brass etc.) including austenitic steels.
