WEBSTER® Hardness Tester Model B-75

Developed to obtain a more sensitive response to slight changes in the upper range of hardness covered by the Model B, the Model B-75 Tester is particularly useful in testing the hardness of stronger aluminum alloys as well as of mild steel. The B-75 covers the range from annealed to full-hard for brass. It is accomplished by incorporating a penetrator of slightly different contours and a heavier load spring than used in the Model B, and the 20 graduations on the dial indicator cover the range between 20 and 100 on the Rockwell B Scale.

Applications for WEBSTER® Hardness Testers:

Can Be Used on Assemblies That Cannot Be Brought to the Labs
Checks for Proper Heat-Treatment Response
Differentiates Between Soft or Work-Hardened Material
Gives a Rapid 100% Check on Parts That Would Normally Take a Long Time to Test
Identifies Heat-Treated Parts
Identifies Parts Made from Improper or Substandard Alloys
Provides Correlation Between a Bench-Mounted Hardness Tester and the Production Line
Segregates Materials in Stock
Useful in Conjunction with Stationary Laboratory Hardness Testing Tools

Model B-75

The WEBSTER® Model B-75 Hardness Tester, P/N: B-75, was developed to obtain more a more sensitive response to slight changes in the upper range of hardness covered by the Model B. This sensitivity is particularly useful in testing mild steel and and the stronger aluminum alloys. For brass the B-75 covers the range from annealed to full-hard. The 20 graduations on the WEBSTER® dial indicator cover the range between 20 and 100 on the Rockwell B Scale. The WEBSTER® Model B-75 Hardness Tester ‘standard configuration’ ships with a 3/8″ anvil and 1/4″ jaw capacity. Other custom anvil and jaw capacity configurations are available, please contact us for a quote. Each tester is shipped in a fitted case with a spare penetrator, adjusting wrench and standard test strip.
