Manual Turret Micro Vickers Hardness Tester – HHV-1000

Manual Turret Micro Vickers Hardness Tester can vary between manufacturers and models. Therefore, it’s recommended to refer to the manufacturer’s documentation and guidelines for the particular instrument you are using for detailed operating instructions and specifications.

key Features

1. Testing Principle: The Vickers hardness testing method is based on the principle of indentation hardness, where a diamond indenter is pressed into the surface of the material being tested. The size of the indentation left by the indenter is measured to determine the material’s hardness.
2. Manual Turret: The term “Manual Turret” refers to the design of the instrument’s indenter and objective lenses. It typically features a rotating turret that holds multiple objective lenses and the diamond indenter. This allows for easy selection and positioning of the desired lens and indenter.
3. Micro Vickers Scale: The Micro Vickers hardness scale is used to measure the hardness of materials with fine microstructures or thin coatings. It utilizes a smaller diamond indenter compared to the regular Vickers hardness scale, resulting in smaller indentations.
4. Hardness Testing Procedure: To perform a hardness test using a Manual Turret Micro Vickers Hardness Tester, the operator typically follows these steps:
   • Prepare the sample surface by ensuring it is clean and flat.
   • Position the sample under the indenter and apply a controlled load.
   • The indenter is pressed into the sample surface for a specified dwell time.
   • The applied load is removed, and the indent is measured using an optical microscope.
   • The diagonal lengths of the indentation are measured and used to calculate the Vickers hardness value.
5. Optical Microscope: It is equipped with an optical microscope to measure the indentation size accurately. The microscope allows the operator to view and measure the indentation using a reticle or digital measurement system.
6. Applications: Micro Vickers hardness testing is commonly used in various industries, including materials science, metallurgy, manufacturing, and research laboratories. It provides valuable information about material properties, such as hardness, elastic modulus, wear resistance, and material behavior under load.
