Brinell hardness tester DHB-3000

benchtopfor non-ferrous metalsbearing

The DHB-3000 is an electronic Brinell hardness tester that incorporates high-sensitivity touch buttons and microcomputer control technology, thereby eliminating the short service life associated with traditional membrane and mechanical pushbuttons. Paired with a precision force-sensor feedback system, it achieves closed-loop, high-accuracy loading control. Integrating optical, mechanical, and electrical technologies, this instrument is primarily used for hardness testing of cast iron, steel, nonferrous metals, as well as hard plastics and bakelite—nonmetallic materials. The device features digital parameter setting, automated loading and unloading sequences, and comprehensive self-diagnostic fault detection. Indentation measurement requires manual operation in conjunction with a microscope. With stable overall performance and user-friendly operation, the DHB-3000 is a fundamental hardness-testing instrument well suited for factory workshops, colleges and universities, and research institutions, offering practical value in industrial quality control and materials research.
