MITECH MHB-3000 Electronic Brinell Hardness Tester

MITECH MHB-3000 Electronic Brinell Hardness Tester

Brand: Mitech
Model: MHB-3000

Product Description

The MITECH MHB-3000 Electronic Brinell Hardness Tester is a robust and highly accurate testing instrument designed to measure the hardness of metals using the Brinell method. Utilizing a hard alloy indenter and electronic automatic loading system, it calculates hardness by measuring the diameter of the indentation left on a material’s surface. Featuring LED digital tube displays and a closed-loop control system, the tester offers intuitive operation and real-time accuracy, making it ideal for both industrial and academic settings.

Built for high-performance applications, the MHB-3000 is suitable for testing materials such as cast iron, steel, and soft alloys, and is widely used in quality control, failure analysis, scientific research, and university laboratories.

Working Principle

The Brinell hardness test applies a specific force (F) through a steel or tungsten carbide ball (D) onto the test material’s surface. After a fixed dwell time, the load is removed, and the diameter of the resulting indentation is measured. This diameter is then used to calculate hardness in HBW units (Brinell Hardness using a Tungsten Carbide Ball).

Working Conditions

• Temperature: 18°C – 28°C

• Relative Humidity: ≤65%

• Environment: Clean, vibration-free, and non-corrosive surroundings required for accurate measurement
