Multifunctional coating thickness tester for metal coatings and plating. It measures the thickness of metal plating and coatings such as paint on steel, enamel, chrome, aluminum, paint and anodized coatings on copper. It automatically detects substrate properties to improve measurement accuracy. Data recording and statistics: It records average, maximum, minimum and difference values at the same time and supports up to 50 data points for statistics, making it easier to track coating quality over time. If there is no activity for 3 minutes, the instrument automatically shuts down to save battery power. Measurement units and speed: The professional coating thickness gauge supports um, mm and mils. Switch units at the push of a button to quickly and accurately measure thickness of plating or coatings on virtually any metal finish. Wide application: Suitable for use in manufacturing, metal processing, commodity inspection and other fields. It is also suitable for laboratory, workshop and outdoor work environments. Use scenarios: - Automotive paint inspection: verify paint thickness on vehicle panels to ensure uniform coverage and meet repair specifications. - Plating quality control: measure thickness of chrome, enamel, aluminum, and copper anodized finishes to ensure adherence to standards. - Incoming/outgoing inspection and lab testing: perform quick thickness checks in manufacturing QC, material testing, and field service environments.
