The high precision LHB 3000A digital Brinell Hardness tester is an electrical control system with a test load applied through a closed-loop control unit to provide precise test force application. With a ten (10) level test force, load selection is done by keyboard and converted to different hardness scales. It is equipped with a 20X magnification microscope to measure the diameter of Birnell indention. The data of test results is displayed on a large LCD screen and output via a printer.
The LHB – 3000A is ideal for testing hardness in industries such as metallurgy, metrology, building materials, research institutes, automotive, railway, energy, steel, aviation, etc,. Materials can be tested such as cast iron, non-ferrous metals, and alloys, quenched and tempered steel, etc,.
