B+ Webster Aluminium Hardness Tester

The Webster hardness tester is a portable instrument for fast hardness inspection of aluminum alloy. The hardness value can be directly read on the dial after one simple press on the handle. The Webster hardness tester conforms to ASTM B647. It is suitable for testing the mechanical performance of the result of heat treatment of aluminum extrusions, sheets and tubes. The typical application is 100% quality inspection as acceptance check at the production line, in the warehouse or in the office.

The new B+ Webster hardness tester features a wear-free nanotechnology indentor. The indentor is so hard that it cuts glass like a diamond tool. It has a guaranteed life of three years, and its actual life is more than five years under normal use condition. This is the first hardness tester indentor in the industry to have a warranty.

A major factor affecting the accuracy of most Webster testers is that when exerting excessive force on the handles after the bottom is felt, the indicator will continue to move half or one graduation higher. This is no longer a problem for the redesigned B+ Tester, and the reading is consistent for all operators.
