Precision coating thickness gauge based on the ultrasonic pulse run-time method.

The QuintSonic 7 enables measurement of up to 5 coatings in a single operation.

It is possible also to measure polymer coatings like paints, varnishes and synthetic materials as well as glass, ceramic or metallic coatings on virtually any substrate. Varnish on synthetic materials, copper on ceramic, synthetic materials on wood, or glass on metal form the typical coating systems that can be measured by the QuintSonic 7.

As the first equipment of its sort, the QuintSonic 7 makes it possible to measure coatings on fibre-reinforced plastics, e.g. GFRP, CFRP, WPC.

The intelligent evaluation of the ultrasonic signal reading allows rapid recording of measured values of over 40 measurements per minute.

Simple calibration and graphic display of the test results on the A screen of QuintSonic 7 enables quick operability and versatile use.


Application

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 5 coatings in a single operation.

Also suited for wall thickness measurement.

Performance features

  • 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.
  • Mere 5 mm measuring area enables gathering measurement on tiny and curved parts
  • Graphic display showing individual coatings, zoom-enabled A screen and menu-driven user guidance
