Overview
SHENYANGTIANXING W-BB75 series Wei-type hardness gauge is divided into two models: W-BB75 and W-BB75b, which are used to test copper pipes of different diameters. It is a testing instrument that can quickly test copper Hardness on site. W-BB75 type is mainly used to detect copper pipes and copper belts, and W-BB75b type is used to test fine copper pipes with an inner diameter of up to 6mm. Easy to use, just clamp the test plate to directly display the Hardness value. High efficiency and Reliability. It is the preferred instrument for inspection of the mechanical properties of copper pipes.
Features
1. The pressure needle is made of imported special steel material and new technology, with high Hardness, good toughness, long life and good interchangeability. Encasement imported from Germany provides comprehensive protection.
2. The pointer assembly uses high-strength pointers, which are not easy to bend and deform after long-term use or wrong operation.
3. The watch window is made of high strength and high toughness Glass, which is not easy to break due to 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 to strictly determine the degree, 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 to ensure high mass.
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 provides fast, non-destructive Hardness detection by clamping the test board and displaying the Hardness value directly.
Applications
Hardness testing of copper pipes, plates and strips, rapid piece-by-piece qualification inspection of batches of products at production sites, sales sites, and construction sites
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. Clamp the test plate with a hardness gauge.
2. Directly read the displayed Hardness value.
Notice
• Ensure that the test plate meets the minimum specimen inner diameter and maximum specimen thickness requirements.
• Regularly use the Wei Hardness block for calibration to ensure measurement accuracy.
• Avoid wrong operation causing the pointer to deform, and store it properly in the instrument case after use.
• Pressure pins and watch window glass are common accessories and need to be checked and replaced regularly.
