W-B75 & W-BB75 Series Webster hardness tester can be used to test the hardness value of copper alloy and brass alloy quickly at the scene of the production. Easy to use, just clamping the work piece firmly, and then read hardness value directly. It is the first choice to test the mechanical property of copper and brass tubes which conform to the China non-ferrous YS/T471-2004
It is used quickly to test the hardness of brass and 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.
High Quality. Well parts processing, precision of whole machine assembly, strict quality inspection, ensure the equipment of high quality.
Conversion. Attached conversion table through product manual or "hardness conversion" mobile applications, Webster hardness value can be converted to Vickers, brinell rockwell hardness value.
Hardness Blocks. Use standard Rockwell hardness tester for sale, in strict accordance with the metro-logical verification regulations. The number and hardness values of laser etching, the validity period of data can be traced to check. The surface roughness and flatness also conform to the requirements of regulations.
