Capable of conducting tests on various loads and indenter diameters, adapting to different materials and testing requirements.
Some portable devices also support other hardness testing methods, such as Rockwell hardness, Vickers hardness, etc.
four
High precision measurement:
Adopting high-precision sensors and digital display systems, it can provide accurate measurement results.
Built in data processing software that can automatically calculate hardness values and generate test reports.
five
Battery powered:
Usually powered by rechargeable batteries, suitable for use on site without power supply.
Long battery life, able to meet long-term testing needs.
working principle:
The working principle of the portable Brinell hardness tester is basically the same as that of the traditional Brinell hardness tester:
one
Prepare the sample: Polish the surface of the metal material to be tested flat to ensure the accuracy of the measurement results.
two
Loading: Select the appropriate load and indenter diameter on the testing machine and apply them to the surface of the material.
three
Indentation measurement: The indenter presses a circular indentation on the surface of the material, and the diameter of the indentation is measured using the built-in measurement system or portable microscope.
four
Calculate hardness: Use the Brinell hardness formula to calculate the hardness value based on the indentation diameter and load.
Application areas:
The portable Brinell hardness tester is widely used in the following fields:
Manufacturing industry: used for quality control and on-site inspection of metal components.
Architecture and infrastructure: used for hardness testing of metal structures such as steel structures, bridges, pipelines, etc.
Maintenance and upkeep: Used for the maintenance and fault diagnosis of mechanical equipment.
Research and development: used for hardness testing in the research and development process of new materials.
advantage:
High flexibility: Testing can be conducted in different locations without the need to bring samples to the laboratory.
Save time and costs: Reduce sample transportation and testing time, improve work efficiency.
Strong adaptability: Suitable for various complex and harsh on-site environments.
matters needing attention:
Calibration: Regularly calibrate the portable Brinell hardness testing machine to ensure the accuracy of measurement results.
Operating standards: Strictly follow the operating manual to avoid measurement errors caused by improper operation.
Maintenance: Regularly clean and maintain to extend the service life of the equipment.

Effortless On-Site Brinell Hardness TestingMake rapid, accurate hardness measurements wherever you need them. This portable machine delivers reliable Brinell hardness testing for large, immovable objects, heavy steel parts, welded areas, and moredirectly in the field. Its manual operation, durable construction, and compact design ensure straightforward and consistent results, even outside the lab.
Versatile and Precise Measurement CapabilityEquipped with selectable 2.5 mm and 5 mm indenter diameters, the tester adjusts seamlessly for various load ranges between 500 and 3000 kgf. The high-magnification (20X) microscope enables precise indentation measurement, while its robust clamp-on mounting accommodates both flat and cylindrical specimens up to 180 mm tall. Ideal for quality control and field inspections.
FAQs of portable brinell hardness testing machine:
Q: How does the portable Brinell hardness tester operate without an external power supply?
A: This machine is manually operated using a lever system, so it does not require any electrical power. The portable design allows you to perform hardness measurements in any environment, making it ideal for on-site field testing and inspections where power sources may not be available.
Q: What is the process for measuring Brinell hardness with this device?
A: To use the tester, clamp it onto your specimen, apply the required test force (between 500 and 3000 kgf) using the manual lever, and create an indentation with either a 2.5 mm or 5 mm indenter. After loading, use the 20X microscope to accurately measure the diameter of the indentation, then reference the Brinell hardness value using the standard calculation.
Q: When should I choose this portable Brinell hardness tester over a bench-top model?
A: This portable tester is best used when you need to test large, heavy, or fixed components that cannot be moved easily to a laboratory. Its perfect for in-situ inspections of metal structures, pipelines, welded joints, and quality control checks directly at the site of construction or manufacturing.
Q: Where can this hardness tester be used?
A: The device is suitable for use in various settings, including manufacturing plants, construction sites, workshops, shipyards, and field inspection locations. Its compact body and carrying case make it convenient for transportation and on-the-go testing in challenging work environments.
Q: What are the main benefits of using this manual Brinell hardness tester?
A: Key benefits include portability, the ability to test without electrical power, suitability for large or immovable objects, robust construction, and high accuracy (1% of reading). It enables single-person operation and delivers immediate, visual/manual results.
Q: Which specimen sizes and shapes can be tested with this machine?
A: This tester accommodates both flat and cylindrical specimens up to 180 mm in height, making it versatile for a wide range of metal components and welded parts. The clamp-on mounting design helps secure the tester for consistent, repeatable results.
Q: What type of results and accuracy can I expect from this device?
A: The tester provides Brinell Hardness values (8-650 HBW) with a measurement resolution of 0.5 HBW and accuracy within 1% of the reading. Results are obtained immediately and measured visually with the supplied microscope.
