Coating Thickness Gauge – MiniTest 2500 – 4500


The MiniTest 2500-4500 coating thickness gauge is the successor to the very popular MiniTest 3100,  it is based on high-precision and modern measuring technology yet is an easy to use, touch-of-a-button operated instrument which meets user requirements for practical, easy application.

Offering a large range of probes (see datasheet in the download section), different calibration methods and evaluation options, the instrument is ideal for a wide range of tasks in the field of coating thickness measurement.

The non-destructive measurement covers the following measuring ranges:

  • 0-50mm for non-magnetic coatings on steel
  • 0-100mm for insulating coatings on non-ferrous metals
  • Heat resistant probes for temperatures up to 250°C and 350°C
  • Pencil shaped probes to measure in tubes and pipes

All probes are equipped with wear resistant poles ensuring long life for use also on abrasive substrates.  Both models are equipped with a huge data memory for storage of up to 2 million measuring values and data transfer to PC is carried out via a USB interface with the MiniTest 4500 additionally offering Bluetooth connectivity.

The MiniTest 2500/4500 is ideal for non-destructive coating thickness measurement of:

  • Non-magnetic coatings on steel
  • Insulating coatings  on non-ferrous metals
  • Copper layers on insulating substrates
  • Powder coatings on steel and non-ferrous metals.
