The AW-20 series Webster Hardness Tester is an instrument that can quickly test the hardness of aluminum alloys in the field.Webster Hardness Tester is easy to use, one card is sufficient, and the hardness value is read directly. For fastTest the hardness of aluminum alloy profiles, tubes, plates, aluminum workpieces and other soft metals.
It is especially suitable for fast,Non-destructive, piece-by-piece conformity inspection.
Pressure needle: The pressure needle made by new materials and new processes has high hardness, long life and good interchangeability.
Pointer: A high-strength pointer that is not easy to bend and deform with long-term use or wrong operation.
Handle: Forged material, anodized upper handle, beautiful, wear-resistant, pollution-resistant.
Hardness block: The standard hardness block is tested by the standard hardness machine.
High quality: fine parts processing, precision machine assembly, strict quality inspection.
Good stability: the full degree point is stable, and the correction point is stable.
