Manually Operated Brinell Hardness Tester – HKB-3000M

Manually operated Brinell hardness tester is a testing device used to determine the Brinell hardness of a material. Unlike hydraulically operated testers, which utilize hydraulic systems for load application, a manually operated tester relies on manual force application and measurement. It is a precision engineered Hardness Testing machine conforming to IS 2281- 2005 & BS 240 and ASTM-E-10. This simple mechanical machine features loading/ unloading through a manually operated lever. It is most suitable for measuring the hardness of steel and other materials of various shapes. These testers offer a cost-effective solution for hardness testing and are suitable for situations where hydraulic systems may not be available or necessary.

Key Aspects and Features

1. Load Application: In a manually operated tester, the load is applied manually by the operator. This is typically done using a lever or a handwheel mechanism, allowing the operator to control and apply the desired load onto the material’s surface.
2. Indenter and Indentation: Similar to other Brinell hardness testers, a manually operated tester uses a hardened steel or carbide ball as the indenter. The operator applies the load manually, creating an indentation on the material’s surface.
3. Measurement: Once the load is applied and removed, the indentation diameter is measured using an optical measurement system or a calibrated microscope. This measurement is essential for calculating the Brinell hardness value.
4. Load Control: While the load application is manually controlled, some manually operated testers may have mechanisms for adjusting and selecting the desired load. This allows for flexibility in testing different materials with varying hardness levels.
5. Operator Skill: As the load application is manual, the accuracy of the hardness measurement is highly dependent on the operator’s skill and technique. Proper training and expertise are required to ensure consistent and reliable results.
6. Portable and Compact: Manually operated Brinell hardness testers are often designed to be portable and compact. This allows for ease of transportation and flexibility in conducting hardness tests in various locations.
7. Versatility: Manually operated testers can be used to test a wide range of materials, including metals, alloys, and industrial components. They find applications in manufacturing, quality control, research, and educational settings.
