Overview
The Webster Hardness Tester (Model W-B75) is a handheld hardness testing instrument designed to quickly detect the Hardness of brass materials in the range of 63 to 105 HRF. It is suitable for workpieces with film thickness 0.4-6 mm and inner diameter greater than 10mm. It is easy to operate, direct reading, high efficiency and Reliability.
Features
1. Wechsler Hardness detection, easy operation and Measurement calibrated.
2. Anodic oxidation treatment, wear-resistant and rust-proof, comfortable feel.
3. Detect a variety of metals, with a wide range of applications.
4. Mechanical design, equipped with a compression spring device, not easily damaged.
5. High toughness surface window glass, Impact resistance is not easy to damage.
6. Clear scale and accurate measurement.
7. Handheld design, easy to use and easy to carry.
8. Hardness values such as Brinell, Rockwell, Vickers, and Wechsler can be converted through the conversion table.
Principle
Webster Hardness Tester uses a mechanical Cedar test principle, which forms a Cedar by applying pressure on the material surface with a crimping pin, and directly reads the Hardness value according to the depth or size of the Cedar. Its compression spring device ensures stable testing and is suitable for rapid non-Destructiveness testing in the field.
Applications
Hardness testing of brass materials, aluminum alloy profiles, pipes, plates, aluminum parts and Miscellaneous softer metals
Standards
American Institute of Materials Standard ASTM B647-10, Nonferrous Metals Industry Standard YS/T420-2000, National Measurement verification code JJG944-1999, National Measurement verification code JJG944-2013
Steps
1. Card the hardness gauge on the workpiece to be tested.
2. Apply pressure until the stylus touches the surface of the material.
3. Directly read the Hardness value displayed by the hardness gauge.
4. If you need Miscellaneous Hardness value, refer to the conversion table for conversion.
Notice
• Only suitable for brass materials with Hardness 63~ 105HRF.
• Film thickness of the workpiece should be within the range of 0.4-6 mm, and the inner diameter should be greater than 10mm.
• Avoid use in extreme environments or overload conditions to prevent damage to the instrument.
• Regular calibrating and maintenance to ensure measurement accuracy.
• Clean the stylus and gauge head after use to keep the instrument in good condition.
