XHB-3000 Digital Brinell Hardness Tester is a advanced instrument integrates the technology of optical, mechanic and electrical and computer. It adopts the motorized testing force application without weight blocks and uses 0.5‰ accuracy compression sensor to compensate the test force lost automatically. The indentation is measured directly in the built-in 20x microscope sensor system, and the LCD screen indicates the indentation diameter and the hardness value. 17 different hardness testing comparison scales can be converted automatically by setup the panel. The load, dwell time and brightness of light can be adjusted on the panel, and an F/ D2 selection table to make the operation ease.
The instrument is equipped with a RS232 serial interface, printer and date storage, it can be connected with PC for readout.

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.
