MiniTest 2500-4500

Provides a large selection of sensors, various calibration techniques, and evaluation options. The non-destructive measurement covers the following measuring range:

  • 0 – 50 mm for non-magnetic coatings on steel.
  • 0 – 100 mm 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 product longevity.


Portable intelligent wireless sensor for non-destructive coating thickness measurement.

  • SmarTest App turns your smartphone or tablet into a measuring device which shows measuring values, statistical evaluation and helps store control and calibration of the sensor.
  • Option to view and process measurement values in metric (μm, mm) or mperial (mils) format.
  • Store and export/download measuring values in CSV format.
Quintsonic T

QuintSonic T

Measures the individual thickness of up to 8 layers on different substrates (e.g. metal, plastics, GFRP, CRFP, WPC, fibre reinforced composites) using the ultrasonic run-time method. Measurement of all layers is performed in one operation. QuintSonic T measures up to eight coatings in a single operation.

  • It measures polymer coatings such as paints, varnishes, and synthetic material, as well as glass, ceramic or metallic coatings on any substrate.
  • Comes with a large 8-inch display, QuintSonic offers a user-friendly overview of the result of measurement as well as the corresponding course of the ultrasonic signal (A-scan).
  • Ideally suited for harsher environments due to IP 67 & MIL-STD 810 G and extremely resistant Gorilla® glass.
Quintsonic 7

QuintSonic 7

For paint, lacquer, and plastic coatings on plastic, metal, wood, ceramic, or glass substrates.

  • Measures polymer coatings such as paints, varnishes, and synthetic material, as well as glass, ceramic or metallic coatings on any substrate.
  • Approximated 10 μm of coating thickness (depending on the ultrasonic velocity in the layer).
  • Extended measuring range up to 7.5mm.
  • Up to 5 layers in one operation.
  • Comply with international standards of DIN EN ISO 2808 (Ultrasonic Reflection).
  • A-Scan on Graphic Display.
Galvano Test


Uses the coulometric method to measure galvanised coatings such as chrome, nickel, cadmium, copper, brass, silver, gold, tin or zinc both on metals and non-metals.

  • Measures almost any electroplated coating/base combination.
  • Suitable for single and multi-layer coatings.
  • Utilises the coulometric principle, a de-plating method conforming to DIN 50 955 and ISO 2177.
  • Suitable for extremely thin coatings starting from 0.05 microns.


Highly durable coating thickness measurement gauge to enable the measurement of non-magnetic coatings on steel using magnetic adhesive force. A metal casing makes it highly robust and resistant against harsh environmental conditions.

  • Non-magnetic coatings such as lacquers, enamels, chrome, and zinc on ferromagnetic basis material (steel)
  • Model NiFe 50: electroplated nickel coatings on steel
  • Models Ni 50 and Ni 100: electroplated nickel coating on non-ferromagnetic substrates (e.g., aluminium, copper, synthetic material, etc.)
Paint Inspection Gauge

Paint Inspection Gauge P.I.G 455

Universal coating thickness gauge utilising the wedge cut method to measure organic coatings on metal, wood, and synthetic material. The P.I.G. is also suitable for multiple coatings.

  • Measurement of non-identified coating materials
  • Measurement of all coatable base materials (wood, synthetic material, metal, etc.)
  • Exchangeable cutter formed of carbide metal
  • Tilt-free cutting guide
  • Integrated microscope with precision vernier
