The digital Brinell hardness tester is an instrument used to measure the hardness of metal materials. It adopts the Brinell hardness test method, which applies a hard sphere of known diameter on the surface of the material, presses it into the material surface under a certain load, and then measures the diameter of the indentation to calculate the Brinell hardness value of the material.
Main features:
one
High precision measurement: Digital Brinell hardness testing machines are usually equipped with high-precision sensors and digital display systems, which can provide accurate measurement results.
two
Automated operation: Modern digital Brinell hardness testing machines typically have automatic loading, unloading, and measurement functions, reducing human operational errors.
three
Data processing capability: These devices are typically equipped with data processing software that can automatically calculate hardness values and generate test reports.
four
Multiple load options: Different loads and indenter diameters can be selected according to different materials and testing requirements.
five
User friendly interface: Most digital Brinell hardness testing machines are equipped with touch screens or computer interfaces for easy operation.
working principle:
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 measures the diameter of the indentation using a microscope or built-in measurement system.
four
Calculate hardness: Use the Brinell hardness formula to calculate the hardness value based on the indentation diameter and load.
