INTRODUCTION
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. MEWOI-ASW20 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. MEWOI-ASW20 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). |

Comparison of Webster Hardness Testers
MEWOI-W20 series aluminum alloy Webster hardness testers have three models: MEWOI-W20 Webster hardness tester is mainly used for inspection of aluminum alloy, tubes and plate, MEWOI-W20A type can be used to inspect industrial aluminum extrusions, plates or parts which of the thickness upper limit to 13mm, MEWOI-W20B type for testing small aluminum profiles or aluminum profiles pipes which of the inner diameter is greater than 6mm. Otherwise, MEWOI-WB75, MEWOI-WBB75 Webster hardness testers for copper alloy, and MEWOI-WB92 Webster hardness tester for stainless steel, respectively suitable for testing the hardness of materials such as copper, brass and mild steel. |
