Features:Thickness gauges are used to measure the thickness of metal coatings and coatings, such as paint/enamel/chrome on steel, paint on aluminum/copper, and anodized coatings. Automatically detects the properties of the substrate.This instrument is used to non-destructively measure the thickness of coatings and paints. It is an indispensable equipment for material surface treatment, widely used in manufacturing, metal processing industry, chemical industry, commodity inspection and other fields, but also in laboratories, workshops and outdoor stable work.Specifications:Product Name: HW-300PRO Coating Thickness GaugeOptional Color: Black / WhiteMaterial: ABSUltra-precision resolution 1um, FE/NFE coating measurement, automotive paint 0-2000umSmall size and high precisionBattery level indicatorAuto shutdown functionFor FE/NFEMeasuring range: 0-2000UMMeasurement accuracy: u00b1 (3%+1UM)Power supply: 2 x 1.5V AAA batteries (shipped without batteries)Use temperature: -10 degrees Celsius 50 degrees CelsiusCertification: CE.FCCPacking size: Length: 128MM*55MM*36MMProduct size: 122MM*50MM*22MMWeight: : 109GPackage included:1 x HW-300PRO Thickness Gauge(Color as your choice)1 x Calibration Piece1 x Manual1 x Color BoxNote:The data is measured manually, and there may be some deviation, but it does not affect the use.
