Article code: W-BB75

The Model BB-75 Tester was developed to answer the need of certain industries for a method of rapidly testing the hardness of electro-deposited copper in the low hardness range. The B-75 penetrator is used to give sensitivity, and the Model 20 load spring is employed to give light pressures. This combination allows the user to test the soft range of many common materials.
Webster hardness tester is easy to operate, just clamp the work piece, and then read the hardness value directly. It focuses on high performance and reliability, in accordance with the Chinese non-ferrous YS/T471-2004 standard.
It is used quickly to test the hardness of copper tubes, sheets and strips, and especially suitable for batch production site and sales site to do the quick testing and non-destructive checking one by one.
conversion: attached conversion table through product manual or "hardness conversion" mobile applications, Webster hardness value can be converted to Vickers, Rockwell and Brinell hardness value.
indenter: special steel, new manufacturing technology, high hardness, good toughness, long service life, good interchangeability.
indicator hand: high strength of pointer, not easy bending deformation after long time using or wrong operation.
dial glass: high strength and high toughness of dial glass, not easy to break after shock.
handle: forged aluminum alloy material, anodic protection, wear-resistant, resistant to pollution.
hardness blocks: use standard Rockwell hardness tester, in strict accordance with the metrological verification regulations. Laser engraving of the serial number, hardness value and validity period of the data. The roughness and flatness of the surface are also in accordance with the standards.
