Shenyang Tianxing W-20 series Wei-style Hardness Tester (also known as Wei-style hardness pliers, Weber Hardness Tester) is divided into three models: W-20, W-20a, W-20b, different models have different uses.
W-20 Webster Hardness Tester is mainly used to detect aluminum alloy building profiles, pipes and plates;
The W-20A model can be used to inspect industrial aluminum profiles, plates and parts up to 13mm thick;
The W-20B model is used to test small aluminum profiles and aluminum pipes with an inner diameter greater than 6mm.
Shenyang Tianxing W-20 series Wei-style Hardness TesterIt can be used to quickly test the hardness of aluminum alloy at the production site, and is the preferred instrument for testing the mechanical properties of aluminum alloy profiles.

Shenyang TianxingW-20 series Webster Hardness Tester is used to quickly detect the hardness of aluminum alloy profiles, pipes, plates, aluminum parts and other soft metals, to judge whether the aluminum profile is aged, whether the aging is qualified, and to distinguish different grades of aluminum and different aging states. Webster Hardness Tester is particularly suitable for fast, non-destructive piece-by-piece inspection of batches of aluminium profiles, windows, doors, windows and curtain walls at the production, sales or construction sites.





1. Pressure needle: The pressure needle made of imported special steel materials and new technology has high hardness, good toughness, long life and good interchangeability. The outer packaging imported from Germany provides comprehensive protection for the pressure needle.
2. Pointer assembly: high-strength pointer, long-term use or wrong operation is not easy to bend and deform.
3. Window: high-strength, high-toughness window glass, not easy to break after impact.
4. Handle: forged aluminum alloy material, anodized upper handle, beautiful, wear-resistant, pollution-resistant.
5. Hardness block: use standard Rockwell Hardness Tester and strictly follow the measurement verification procedures for calibration. The number and hardness value of laser etching, and the traceability data can be checked within the validity period. The surface roughness and flatness meet the requirements of the regulations.
6. High quality: fine parts processing, precision machine assembly, and strict quality inspection ensure the high quality of the instrument.
7. Good stability: the full degree point is stable, the correction point is stable, and the pointer has no "crawling".
8. Easy conversion: Through the conversion table attached to the product manual or the "hardness conversion" mobile phone application, the Webster Hardness value can be converted into Vickers, Rockwell, Brinell and other hardness values.
9. Portability: The high-quality portable instrument case and well-fitting buffer sponge provide portability for the W-B20 series Webster Hardness Tester while protecting the W-20 series Webster Hardness Tester as much as possible.
