Description: The thickness gauge is used to measure the thickness of the plated and coated sheet on metal, e.g. paint/enamel/ chrome on steel, paint and anodizing coating on aluminum/copper. The measuring range is 0-2000UM. The gauge takes the precision integrated probe, and uses principles of electro-magnetic induction and the eddy current effect, which automatically detects the attribute of substrates. The Gauge is designed for non-destructively measuring the thickness of coating and painting. It is essential for material surface treatment and widely used in manufacturing industry, metal-processing industry, chemic industry, commodity inspection area Specification: Product name: HW-300 coating thickness gauge Size: 110x52x25mm/4.3x2x1 inch Material: ABS Resolution: 0.01mm/1mil Measuring range: 0-2000UM Measurement accuracy: ±(3%+1UM) Power supply: 2 1.5V AAA batteries (not included) Operating temperature: -10 degrees Celsius 50 degrees Celsius Package Includes: 1 x Thickness gauge 1 x Manual 1 x Calibration sheet
