The DHT-20 is an advanced portable hardness tester,
characterized by its high accuracy, wide measuring
range and simplicity of operation. It’s designed to
measure the hardness of ordinary metals and is widely
used in quality and test and measurement laboratories
in industries such as petroleum, chemical processing,
machinery, heat treating, and electric power.
The DHT-20 uses the Leeb Hardness testing
procedure. To determine the target’s Leeb hardness
value, a parameter designated HL, is determined by
using the plungers rebound velocity and an algorithm
in the DHT-20. These can be displayed in a variety of
units. The operator’s manual includes a hardness table
of typical industrial materials as a reference guide.
