The Analog Rockwell Hardness Tester is constructed with high-quality materials and features a durable, compact design that is easy to use and maintain. The device is equipped with an analog display that provides accurate and reliable readings, making it an ideal tool for quality control and testing applications in a variety of industries. This hardness tester is suitable for use with a wide range of metallic materials, including steel, aluminum, brass, and copper. It is also capable of measuring the hardness of heat-treated materials and can be used to test the hardness of thin materials, such as sheet metal.

A Rockwell Hardness Tester is a device used to measure the hardness of materials, such as metals, plastics, and ceramics. The tester determines the material's resistance to penetration under a specific load and provides a direct hardness value.

1. Working Principle:

   • Measures the depth of penetration of an indenter into the material under a specific load.
   • The hardness is displayed on a dial or digital screen as a Rockwell Hardness Number (HR).

2. Indenters:

   • Steel Ball Indenter: For softer materials like plastics or softer metals.
   • Diamond Cone Indenter: For harder materials like steel or hard alloys.

3. Load Application:

   • Uses different loads (measured in kilograms or Newtons) depending on the material and Rockwell scale being used.
   • Common loads: 60kgf, 100kgf, 150kgf.

4. Scales:

   • The Rockwell Hardness test uses multiple scales (e.g., A, B, C, etc.), depending on the material and type of indenter.
     • HRC (Rockwell C Scale): Used for harder materials like hardened steel.
     • HRB (Rockwell B Scale): For softer materials like aluminum or brass.

5. Types:

   • Analog Rockwell Tester: Displays results via a manual dial gauge.
   • Digital Rockwell Tester: Provides a digital readout of hardness values.
   • Portable Rockwell Tester: Compact devices for on-site testing.

6. Applications:

   • Quality control in manufacturing industries.
   • Material testing in metallurgy, engineering, and research laboratories.
   • Evaluation of material wear resistance and strength.

7. Advantages:

   • Simple, fast, and direct measurement.
   • Non-destructive testing method.
   • Suitable for a wide range of materials.
