Rockwell Hardness Tester – HRHT-150 A
Our model HRHT-150 A hardness testers are manually operated tester is useful for checking the hardness of very thin sheets and surface hardness and suitable for testing the hardness of metals and alloys of all kinds, hard or soft, whether flat or round etc. or of irregular shape. These Testers are simple in design and easy to operate, still yet quite sensitive and accurate. This model conforms to IS: 1586-2000, BS: 891 part 1&2. Rockwell Hardness Tester is a mechanical testing instrument used to measure the hardness of materials, particularly metals. It is named after the American metallurgist and engineer Stanley P. Rockwell, who invented the Rockwell hardness testing method in the early 20th century. The Rockwell hardness test is one of the most commonly used methods for determining the hardness of metals due to its speed, simplicity, and accuracy.
Main Components
- Indenter: The indenter is a hardened steel or diamond ball, or a conical diamond, which is pressed into the material to create an impression.
- Anvil: The anvil is a flat and rigid surface on which the material being tested rests to ensure stability during the test.
- Minor Load: The minor load is the initial, smaller load applied to eliminate any surface irregularities or roughness before the major load is applied.
- Major Load: The major load is the larger load applied to create the indentation in the material.
- Dial or Digital Display: The Rockwell Hardness Tester features a dial or digital display that indicates the hardness value after the test is conducted.
- Depth Measurement: The tester includes a mechanism to measure the depth of the indentation, which is used to calculate the hardness value.
