Webster hardness testers also known as Webster hardness pliers, they can be used to test the hardness value of aluminum alloy quickly at the scene of the production. They are the preferred instruments for testing the force of aluminum alloy. W-20 Webster hardness tester can be used to test the hardness value of aluminum alloy, pipe, plate, aluminum parts, and other soft metals. Judge whether the aluminum products have the aging or not, and determine the limitation is up to standard. It also can distinguish between different types of aluminum and different aging state. Webster hardness testers especially suitable for batch production site and sales site, also for the aluminum profile, door, window, curtain, wall and so on to do the quick testing and non-destructive checking one by one. Webster hardness tester is easy to operate, just clamp the work piece, and then read the hardness value directly. It focus on high efficiency and good reliability which conform to the China non-ferrous YS/T420-2000 and American standard ASTM B647-84 (2000).

Features

1Indenter Adopt import special steel material, New technology of manufacturing, High hardness, good toughness, Long life, good interchangeability. Germany imported packaging, To provide comprehensive protection for the indenter.

2Indicator Hand High strength of pointer, Not easy bending deformation after long time using or wrong operation.

3Dial Glass High strength and high toughness of dial glass, Not easy to break after shock.

4Handle Forged aluminum alloy material, Anodic oxidation handle, Beautiful, wear-resistant, resistant to pollution.

5Hardness Blocks Use standard Rockwell hardness tester, In strict accordance with the metrological 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.

6High – quality Well parts processing, Precision of whole machine assembly, Strict quality inspection, Ensure the equipment of high quality.

7Stability Stability of full scale value, Calibration point stability, Pointer no "crawl".

8Conversion Attached conversion table through product manual or "hardness conversion" mobile applications, Webster hardness value can be converted to Vickers, Rockwell and Brinell hardness value.

9Portability The high quality portable instrument box Perfect fit sponge for buffer Not only provides portability for instrument but also supply the maximum protection at the same time.
