The Touchstone 1 is a high performance, low cost, simple to use handheld thickness gauge and it is suitable for use in a variety of applications in NDT (non-destructive testing) and is capable of measuring most engineering materials including plastic, glass, copper, cast iron and aluminium as well as a wide range of steels. The Touchstone 1 wall thickness gauge is simple to calibrate and operate; and produces accurate and reproducible results. The Touchstone 1 is widely used in ultrasonic thickness testing in quality control during marine maintenance, manufacturing and as an inspection tool to measure remaining wall thickness of materials subject to erosion and corrosion.
If you need to measure the coating on a ferrous i.e. steel substrate, like the paint on a ship’s hull, then a simple way to do this is to use our Touchstone 2 coating gauge.
