Thickness gauges are used to measure the thickness of metal coatings and coatings such as paint/enamel/chrome on steel, paint and anodized coatings on aluminium/copper. Automatic detection of substrate properties.This instrument is used to non-destructively measure the thickness of coatings and paints.It is an essential equipment for material surface treatment, widely used in manufacturing, metal processing industry, chemical industry, commodity inspection and other fields, and can also work stably in laboratories, workshops and outdoors.Ultra-precision resolution 1um, FE/NFE coating measurement, automotive paint 0-2000umSmall size and high precisionbattery level indicatorAutomatic shutdown functionfor FE/NFEMeasuring range: 0-2000UMMeasurement accuracy: (3%+1UM)Power: 2 1.5V AAA batteries (without batteries)Use temperature: -10 degrees Celsius 50 degrees Celsiussize: 122 x 50 x 22MMMaterial: plasticcolour: WhitePackage Contents:1 x thickness gaugeOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
