Coating thickness measurement  MiniTest 2500/4500


Classic Design
  • All functions directly accessible
  • Large selection of interchangeable sensors
  • High-contrast display and illuminated keypad
  • Memory and Statistics
  • Bluetooth and USB Output
  • IP 65 Rated Rugged housing

Connect the MiniTest 2500 or 4500 directly to your computer (like a USB key) and you will read the data into the files.
So, a software is no longer necessary.

In addition, the MiniTest 4500 also offers bluetooth so with the MiniTest 4500 you can also use the MiniView App (to download on GooglePlay for free) for a transfer data on your computer, on your tablet or smartphone.

Precision gauges »Made in Germany« since 1947
The portable coating thickness gauges MiniTest 2500 and MiniTest 4500 measure non-destructively using either magnetic induction or the eddy current principle.
The gauges are useful for  a wide range of applications where high precision coating thickness measurement is required including : industrial corrosion, protection, decorative coatings in design sector, or daily use by:
  • Manufacturers and end-users of all types of coated products
  • Auditors and inspectors
  • Electroplating and paint shops
  • Chemical industry
  • Automotive production, ship building, aviation, plant and mechanical engineering

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 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 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.
  • FN-type sensors combine both principles and identify the substrate underneath the coating thus automatically switching to the correct measuring principle to measure on base material steel or non-ferrous metal.
