QuintSonic T Ultrasonic Coating Thickness Gauge

QuintSonic T Ultrasonic Coating Thickness Gauge


 The QuintSonic T combines measuring system and evaluation software in an ultrasonic sensor directly connected to an industrial tablet. QuintSonic T measures the individual thickness of up to 8 layers on different substrates (e.g. metal, plastics, GFRP, CRFP, WPC, fiber reinforced composites) using the ultrasonic run-time method. Measurement of all layers is performed in only one operation.

Precise and easy to handle, QuintSonic T can measure all typical coating systems such as:

  • Lacquers on synthetic material
  • Synthetic material on wood
  • Glass on metal





All Measuring Parameters on One Screen

QuintSonic T measures of up to eight coatings in a single operation. It can measure polymer coatings such as paints, varnishes and synthetic material, as well as glass, ceramic or metallic coatings on virtually any substrate. Featuring a generous 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). Parameters for signal adjustment are displayed simultaneously and can be adapted to the current measurement with significant time savings. Subsequent adjustment of parameters is also possible through the new memory option for A-scans. In addition, QuintSonic T is characterized by simple handling via touch screen and intuitive user guidance. The measuring program also offers a clear data structure with integrated test report generation. QuintSonic T is also ideally suited for harsher environments due to IP 67 & MIL-STD 810 G and extremely resistant Gorilla® glass.


Non-destructive measurement of:

  • Varnish, synthetic materials, glass, enamel and other coatings on wood, synthetic materials, glass, metal and ceramic
  • Metal coatings on synthetic materials, ceramic and wood
  • Up to 8 coatings in a single operation.


  • Quick evaluation of the measuring signal, high accuracy and repeatability owing to the sensor-integrated digital 32-bit signal processing (SIDSP®)
  • Over 40 measuring values per minute: start, wait for 1 second, done.
  • 5 mm measuring area enables gathering measurement on tiny and curved parts.
