Product Description

The Sonohard High Resolution portable hardness tester SH-21 series differs from traditional hardness testers. Instead of measuring the size of the indentation of the test sample using a microscope, it uses a diamond indenter equipped with a vibrating rod that presses on the test surface at a fixed load and then measures its hardness by applying ultrasonic vibrations and analyzing its damping effect.The technique is very reproducible which makes the SH21 a perfect tool for on-site measurements as for example maintenance of large scale structures, vehicles, ships, steel towers, bridges, aviation aircraft. It is ideal for inspection of difficult to get area such as crank shaft metal casts, gears and grooved area.

Two models available:

SH-21-E1; 1kg load

SH-21A-E2; 2kg load
