HB-3000 Digital Brinell Hardness Tester

The HB-3000 digital Brinell hardness tester adopts electronic closed loop design, which contributes to light weight and accurate measurement. Its outstanding software design facilitates operation and guarantees high performance.

The hardness tester makes use of Brinell hardness measurement principle, and is appropriate for unhardened steel, cast iron, nonferrous metal, soft bearing alloy and other materials. Its maximum test force reaches up to 3000kgf. The Brinell hardness test may create deep indentation that will not influenced by microstructural segregation, large crystal grain or uneven components of specimens. Therefore, the measuring instrument is able to exactly measure the hardness of cast iron, cast steel, forged steel and other materials with coarse grains. Compared with general portable durometers, it successfully avoids errors.

Features
1. The hardness tester is provided with fine machinery structure and microcomputer close loop control system, which ensures precision control over test force. It leaves out traditional weight loading steps.
2. Controlled by a microcomputer, it automatically loads, dwells and unloads.
3. There are 10 grades of test force. The operator can switch the test force through the button.
4. Its high brightness LCD can clearly display test parameters, including test force, duration time, indenter kinds, operation tips and other information.
5. Its weight is 50% lighter than that of many like products.
6. It does not require the operator to move weights, considerably reducing his labor intensity and eliminates potential safety hazard.
7. The 20X reading microscope is able to correctly read indentation diameter.
8. The hardness tester innovatively has hardness calculation function, so as to intelligently calculate hardness values.
