The QuintSonic-7 is a Multi-Layer Ultrasonic Coating Thickness Gauge, specially designed for non-destructive coating thickness measurements of paint, varnish, plastics, and other insulation coatings applied on wood, plastics, glass, ceramics, etc. as well as for polymer layers on metals. Up to now, these materials could only be measured destructively. The QuintSonic-7 features a simple calibration and graphic display of test results on an A screen making it a highly versatile gauge that is quick to use. The QuintSonic-7 enables the measurement of up to 5 coatings in a single operation. As a special feature, the gauge offers the possibility to measure the total thickness as well as the individual layers of a multi-layer system in only one measuring process. The QuintSonic-7 coating thickness gauge measures single and multi-layers of coatings up to a total thickness of 7.5mm / 0.29". The robust gauge is appropriate for use in the laboratory, in production, and on-site.
