Product Description
 
Closed-loop Digital Brinell Hardness Tester

1. The product body is formed by a casting process and undergoes long-term aging treatment. Compared with the panel process, the shape change during long-term use is minimal, and it can effectively adapt to a variety of harsh environments.

 

2. The surface uses automotive-grade paint, which is high in quality and highly scratch-resistant. It remains bright and like new even after many years of use.

 

3. The structure is solid, with good rigidity, high accuracy, reliability, durability, and testing efficiency.

 

4. The control panel separates strong and weak electrical phases to avoid mutual interference and prevent breakdown due to excessive current, thereby improving operational safety and extending panel lifespan.

 

5. The high-power solid-state relay offers high power output, low power consumption, no contact or sparks, high isolation between control circuits, and a long service life.

 

6. A large-torque permanent magnet synchronous motor replaces the traditional speed reducer, significantly reducing machine noise and lowering the failure rate.

 

7. Accuracy complies with GB/T231.2, ISO 6506-2, and ASTM E10 standards.

Applications

 

 

1. Measure Brinell hardness of ferrous metal, non-ferrous metal and bearing alloy materials;
2. Carbide, carburized steel, hardened steel, surface hardened steel, hard cast steel, aluminum alloy, copper alloy, malleable casting, mild steel, tempered steel, annealed steel, bearing steel, etc.

 

Brinell hardness tester: the steps
 

The Brinell test can be simply explained as an indentation hardness test consisting of two basic steps.

Step one

Using a known indenter and a known force; apply the known force through the known indenter perpendicular to the material under test and hold the known force for specified amount of time(dwell).

Step two

Measure the diameter of the resulting indentation in at least two directions perpendicular to each other. The Brinell hardness value is then computed from the mean of the diameter measurements by the use of a mathematical formula designed for this purpose, or more frequently from a chart based on the formula.

 

How to use a Brinell tester for accurate results
 
Manual Brinell Hardness Measuring Equipment

To achieve accurate results using a Brinell hardness tester, it’s important to follow best practices in preparation and measurement. Begin with a clean, flat surface to ensure proper contact between the material and the indenter. Even though Brinell is forgiving of surface imperfections, debris or heavy oxidation should be removed.

Next, select the correct indenter and test load based on the material type and size. Using the wrong configuration may result in inaccurate or unreadable impressions. For most steel applications, a 10 mm carbide ball with a 3000 kgf load is standard.

After the test force is applied and held for the appropriate dwell time, measure the diameter of the indentation along two perpendicular axes. Average these values to calculate the BHN. Modern Brinell testers may include integrated optical systems or software that automates this measurement and calculation process.

Accuracy also depends on equipment condition and calibration. UPI Laboratories provides certified Brinell indenters and reference blocks that meet ISO and ASTM requirements. Each item is calibrated under ISO/IEC 17025 RvA accreditation, providing full traceability and confidence in your measurements.
