W-B75 Web Hardness Tester

Name: W-B75 Web Hardness Tester
Brand: Beijing Lanetech Square Co., Ltd.

W-B75 Brass Alloy Webster Hardness Tester: Rapid On-Site Quality Assurance

The W-B75 Brass Alloy Webster Hardness Tester is specifically engineered for high-efficiency, on-site hardness testing of brass alloys directly on the production floor. Its operation is remarkably simple: position the sample between the anvil and indenter, then apply pressure to the handles until a distinct "bottom" sensation is felt, at which point the dial indicator provides the direct hardness reading.

As the instrument of choice for evaluating brass alloy strength, the W-B75 is indispensable for measuring the hardness of brass pipes, plates, and components. It is exceptionally valuable for conducting swift, non-destructive tests in mass production and sales environments, enabling 100% piece-by-piece quality verification to ensure every brass product meets stringent standards. Designed for maximum reliability, it adheres to the Chinese non-ferrous standard YS/T471-2000.

Features of W-B75 Web Hardness Tester

1. Indenter

Crafted from imported specialty steel using advanced manufacturing techniques, the indenter delivers superior hardness and exceptional toughness. This results in an extended service life and excellent interchangeability. Each indenter is packaged in protective German-made packaging for comprehensive protection.

Indenter

2. Indicator Hand

The high-strength pointer is highly resistant to bending or deformation, even after prolonged use or accidental mishandling, ensuring long-term accuracy.

Indicator Hand

3. Dial Glass

Made from high-strength, high-toughness glass, the dial window is highly resistant to breakage from impacts, providing durable protection for the gauge.

Dial Glass

4. Handle

The handle is forged from aluminum alloy and undergoes anodic oxidation, resulting in a user-friendly grip that is highly wear-resistant and resistant to contamination.

Handle

5. Hardness Blocks

Supplied with standard Rockwell hardness blocks, manufactured in strict accordance with metrological verification regulations. Hardness values are laser-etched for permanence, and all data is traceable within its validity period. Surface roughness and flatness fully comply with regulatory requirements.

Hardness Blocks

6. High-quality

High-precision component processing, meticulous machine assembly, and rigorous quality inspection collectively ensure the instrument meets the highest standards of quality and performance.

High-quality

7. Stability

Excellent stability across the entire measurement scale and at all calibration points. The pointer moves smoothly without any "sticking" or "crawling," guaranteeing reliable and consistent readings.

Stability

8. Conversion

A detailed hardness conversion table is provided in the product manual and via a dedicated "Hardness Conversion" application, enabling easy conversion of Webster hardness values to Vickers (HV), Rockwell (HRC, HRB), and Brinell (HB) scales.

Conversion

9. Portability

The kit includes a high-quality portable case with custom-fit sponge cushioning. This design not only ensures excellent portability but also provides maximum protection for the instrument during transport and storage.
