Portable Metal Hardness Tester

The portable metal hardness tester is a portable hardness measuring instrument, which can measure a variety of metal materials conveniently and quickly.

Product description

Parameters

Product Description:
The portable metal hardness tester is a portable hardness measuring instrument, which can measure a variety of metal materials conveniently and quickly. And it can be freely converted between different hardness systems, tolerance limits can be set in advance, and an alarm will be automatically sent out of the range. It has the characteristics of high test accuracy, small size, easy operation, convenient carrying, and wide measurement range. It is based on the principle of Leeb hardness, the measured Leeb (HL) hardness value is automatically converted into Brinell, Rockwell, Vickers, Shore and other hardness values through the program. Various test accessories can also be configured to satisfy each Kind of test conditions and environment. It is mainly suitable for rapid hardness testing of metal materials, especially suitable for field hardness testing of large parts and non-detachable parts.
