RS PRO 200mm Imperial & Metric Depth Gauge, Stainless Steel, With UKAS Calibration

This depth gauge from RS PRO can be used to measure the depths of spaces up to 200 mm deep. It's highly accurate to within ±0.001 mm. As it's made from tough, corrosion-resistant hardened stainless steel, this gauge is long-lasting, even when used for heavy-duty applications.
The gauge is powered by a SR44/1.55 V silver oxide battery, so you don't need to plug it in. It's fitted with a knurled locking screw that makes it easy to fix your measurements. The end of the shaft is fitted with a hook so you can easily align it with the lip of a space. Its digital display gives both metric and imperial readings.
It meets the American National Standards Institute (ANSI) ESD S20.20:2014 and British Standard EN 61340-5-1:2007 electrostatic control standards, meaning it won't damage equipment via electrostatic discharge. A gauge of this kind is an invaluable tool for workshops or machine shops.
