Overview
SHENYANGTIANXING W-B75b Webster Hardness Tester is a Hardness testing instrument specially designed to detect the mechanical properties of brass alloys, with a measurement range of 0-20HW. This model is especially suitable for testing brass thin pipes with an inner diameter of up to 6mm. It can quickly test brass Hardness on site. It is easy to use. The Hardness value is directly read out, with high efficiency and good Reliability.
Features
1. The pressure needle is made of imported special steel material, which has high Hardness, good toughness, long life and good interchangeability. Encasement imported from Germany provides comprehensive protection.
2. The pointer assembly adopts high-strength pointers, which are not easy to bend and deform after long-term use or wrong operation.
3. The table window is made of high strength and high toughness Glass, which is not easy to break after Impact.
4. The handle is made of forged aluminum alloy material, anodic oxidation treatment, beautiful, wear-resistant and pollution-resistant.
5. Hardness block uses standard Rockwell hardness tester, laser etching number and Hardness value, Traceability data can be checked, surface roughness and Smoothness meet the requirements of the regulations.
6. Fine parts processing, precision machine assembly and strict mass inspection ensure the high mass of the instrument.
7. Stability is good, the fullness point and correction point are stable, and the pointer does not "crawl".
8. The conversion is convenient. The Wechsler Hardness value can be converted into Vickers, Rockwell, Brinell and other Hardness values through the manual conversion table or mobile phone application.
9. Good portability, equipped with high-mass portable instrument case and buffer sponge, easy to carry and protect the instrument.
Principle
Webster Hardness Tester evaluates the hardness of materials by applying pressure on the specimen with a crimping pin and measuring Crain Depth or related parameters. The instrument directly reads the Hardness value for fast non-Destructiveness detection.
Applications
Rapid Detection of the Hardness of Copper Alloy Pipes, Sheets and Strips, Production Site, Sales Site, Acceptance Site Rapid Non-Destructiveness Qualification Inspection of Batches of Products
Standards
Non-ferrous metal industry standard YS/T 471-2004 "Wechsler Hardness Test Method for Copper and Copper Alloys", National Measurement verification code JJG944-2013 "Metal Webster Hardness Tester"
Steps
1. Card the hardness gauge on the sample.
2. Directly read the Hardness value.
Notice
• Make sure that the inner diameter of the sample is not less than 6mm and the thickness is not more than 8mm.
• Check the status of the crimp and pointer components before use.
• Avoid Undue Impact on Surface Glass.
• Regularly calibrate using standard Hardness blocks.
• Refer to manual or mobile app when converting Hardness value.
