WEBSTER® Hardness Tester Model BB-75

Certain industries needed a method of rapidly testing the hardness of electrodeposited copper in the low hardness range. The Model BB-75 Tester was the solution. This penetrator is used to give sensitivity while the Model B load spring is employed to give light pressure. This combination allows users to test the soft range of many common materials. The graph below shows the range covered by this tester on copper.

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
