Description Features 1. Automatic Detection: Layer thickness gauge designed with dual technology, the non-destructive layer thickness tester removes the work of testing surface coatings by providing automatic recognition for both ferrous and non-ferrous substrates. 2. High Accuracy: Our testing instrument is highly accurate, thanks to its compatibility with digital layer thickness gauges. 3. Easy-to-Read Display: Color layer thickness gauge with its large screen displays metal type, working mode, number, battery status, and readings in either um or mil units. 4. Convenient and Usability: It is a highly accurate and compact instrument used to quickly and accurately measure the thickness of coating or plating on all types of metal surfaces. Can make quick and effective measurements of surfaces of any shape - concave, rough, and convex, thanks to the dynamic design of the measuring sensor. 5. Wide Application: This device can be used to determine the average thickness of paint on a car body, used by amateurs and professionals in manufacturing, shipbuilding, workshops, painting shops, aerospace industries, in the automotive industry, etc. Specification Material: ABS Color: White, Black Package Size: 12*5*2 cm Weight: 95 g Battery: 2 AAA batteries (Not Included) Voltage: 1.5 v Test Range: 0-2000 um Test Accuracy: 3%+1 um Operating Temperature: -10 -50 ℃ Packaging: Color Box Package Includes: 1 Layer Thickness Gauge 1 Calibration Sheet 1 Instruction
