Brinell hardness tester DHB-3000T

benchtopdigital displaydigital

Product Overview
The DHB-3000T is an electronic Brinell hardness tester combining high-sensitivity physical touch buttons with a touchscreen and a precision load-transducer feedback system to provide closed-loop, high-accuracy load control. Integrating optical, mechanical and electronic technologies, it is intended for hardness testing of cast iron, steel, nonferrous metals and nonmetallic materials such as rigid plastics and bakelite. The instrument supports digital parameter setting, automated loading/unloading sequences and comprehensive self-diagnostic fault detection. Indentation measurement requires manual operation with the included microscope. Stable performance and straightforward operation make it suitable for factory workshops, laboratories and research institutions.

Product Advantages

• Dual-control interface: highly sensitive physical touch buttons combined with a touchscreen for improved reliability and operational flexibility.
• Touchscreen provides automatic calculation and immediate display of hardness values for efficient workflow.
• Closed-loop load control via precision load-transducer for high-accuracy loading.
• Durable design and easy-to-clean surfaces to mitigate shortened button lifetime and degraded responsiveness in harsh environments.
