Overview
Webster Hardness Tester (Model W-20b) is a portable instrument for rapid testing of aluminum alloy Hardness in the production field, which can inspect the mechanical properties of aluminum alloy profiles. It is easy to use, can directly read the Hardness value with one card, high efficiency and Reliability, conforms to the Chinese non-ferrous metal standard YS/T420-2000 and the American standard ASTM B647-84 (2000), and can measure the workpiece size Film thickness 0.4-8 mm, inner diameter > 6mm.
Features
1. Wechsler Hardness Easy to Detect and Measurement.
2. Through anodic oxidation treatment, wear-resistant and rust-free, comfortable feel.
3. Detect a variety of metals, Hardness detection has a wide range of applications.
4. Mechanical design, compression spring device, not easy to damage.
5. High toughness surface window glass, Impact is not easy to damage.
6. Clear scale and accurate measurement.
7. Easy to use, handheld design, easy to carry.
8. Conversion is convenient, and Hardness values such as Brinell, Rockwell, Vickers, and Wechsler can be obtained through the conversion table.
Principle
Webster Hardness Tester uses a mechanical design to apply pressure to the workpiece through a compression spring device to form a Crowd and directly read the Hardness value. It is based on the principle of Crowd hardness testing and is suitable for rapid, non-Destructiveness testing of softer metals such as aluminum alloys. Hardness.
Applications
Hardness Testing of Aluminum Alloy Profiles, Pipes, Sheets, Aluminum Parts and Miscellaneous Soft Metals
Standards
YS/T420-2000、ASTM B647-84(2000)、ASTM B647-10、YS/T420-2000、JJG944-1999、JJG944-2013
Steps
1. Attach the Webster Hardness Tester to the workpiece to be tested.
2. Apply pressure so that the crimp contacts the workpiece surface.
3. Directly read the Hardness value on the dial.
4. To convert Miscellaneous Hardness values, use the conversion table to convert.
Notice
• Ensure that the workpiece size meets the requirements: Film thickness 0.4-8 mm, inner diameter > 6mm.
• Hardness testing only for aluminum alloys and Miscellaneous softer metals.
• Check whether the instrument is in good condition before use to avoid damage to the pressure needle or watch glass.
• Regularly calibrate instruments to ensure measurement accuracy.
Store in a drying environment to prevent corrosion.
