DHB-3000 Electronic Brinell Hardness Tester is a advanced product integrate the precision mechanical structure with the computer control by means of the mechanical and electrical circuit system. It adopts the motorized test force application without weight blocks, and uses 0.5‰ accuracy compression sensor and the CPU control system to compensate the test force lost automatically during the testing. The test force and the load dwell time can be directly setup in pressing the selected keys on the panel with reliable repetition, precise reading and easy operation.

Usage Range:
Brinell indentation is the largest indentation among all the hardness testing, it is able to reflect the comprehensive features of the material, and the testing is unaffected by the macrostructure and the compositional unevenness of the specimen, hence it is a reliable hardness testing with high precision. The Brinell hardness testing is widely used in such industrial fields as metallurgy, forging, casting, unhardened steel and nonferrous metals industries, as well as in the laboratories, colleges and scientific research institutes.
