Overview

The TH190 Leeb hardness tester (pen type hardness tester, pocket type hardness tester) is ultra portable, with an integrated probe host design that avoids the problem of broken wires in the split type connection of the host probe, enabling one handed operation and a fully metal shell; durable. It can measure Leeb, Brinell, Rockwell B, Rockwell C, Vickers, and Shore hardness and can convert them to each other.
