Webster Hardness Tester is an instrument that can promptly on-site test the hardness of aluminum alloy material, including section bar,tubes,plates,aluminum parts,and hardness of other soft mental. It is such an instrument convenient in usage, with a simple “clamp” and direct result-reading, that it always receives good feedback of high efficiency and strong stability.

Webster Hardness Tester is the best choice for mechanical testing on aluminum alloy material, it is conform to Chinese nonferrous standard YS/T420-2004 and US standard ASTM B647-84(2000).

Using Scope:

Especially suitable in production site,sales site or construction site for quickly testing on bulk products with non-destructive quality inspection piece by piece.

Besides aluminum alloy material, it is also suitable to test red copper, brass, soft copper etc.


*W-20: General Model, suitable for common aluminum materials;

*W-20A:Suitable for aluminum materials with thickness 13mm;

*W-20B:Suitable for aluminum tube with inner dia.≥6mm;
