Its basically like sonar. Sending a signal and bouncing it back through the material will vary in time it takes to receive the PING. The longer it takes to receive the PING, the harder the material.
Another Answer:
The common hardness test is the Indent Test. This test is used in relation to the Rockwell Hardness Scale. The instrument holds a probe called an Indenter. The machine is like a press that pushes the Indenter into the material at a known force. The depth of the indentation made in the material is a measure of its hardness on the Rockwell Hardness Scale.

What is the difference between brinell and rockwell hardness tester?
Brinell hardness tester uses a ball to apply a specified load on the material surface, measured by the resulting indentation size. Rockwell hardness tester uses a diamond cone or steel ball to penetrate the material, and hardness is calculated based on the depth of penetration. Brinell is better for softer materials and larger test areas, while Rockwell is more versatile and provides different scales for various materials.
Why is the spring of the hardness tester never be left under tension?
Leaving the spring of the hardness tester under tension for extended periods can lead to deformation or permanent set, affecting its accuracy and reliability. Releasing the tension when not in use helps maintain the spring's elasticity and ensures consistent hardness test results.
Why diamond is used in Rockwell hardness tester?
Diamond is the hardest known material, which allows it to exert a uniform and stable pressure on the test material during the Rockwell hardness testing process. This ensures accurate and consistent hardness measurements across different samples. Additionally, diamond has low wear characteristics, making it ideal for repeated and long-term use in hardness testing.
What is the working principle of a floating buoy?
A floating buoy works on the principle of buoyancy, which is based on Archimedes' principle. The buoy floats on water due to the displacement of water equal to its weight, creating an upward force that opposes the gravitational force pulling it down. The buoy's shape and material help it displace water efficiently to stay afloat.

What is a Brinell hardness tester used for?
The Brinell hardness tester was invented to measure the hardness of materials using an indentation. Applied force is measured against the force, diameter of indentation and indenter.
