Product overviewQuintSonic 7 is an ultrasonic coating thickness gauge that established new standards for non‑destructive measurement of polymer and metal coatings. As the first gauge integrating a digital ultrasonic sensor, it evaluates up to five individual coatings on metallic and non‑metallic substrates and offers reproducible results, simple calibration and a graphic A‑screen. The model has been succeeded by QuintSonic T.
Applications- Non‑destructive measurement of varnish, plastics, glass, enamel and other coatings on wood, plastics, glass, metal and ceramics
- Measurement of metal coatings on plastics, ceramics and wood
