hardness tester manufacturer

Introduction

W-20 Aluminum Alloy Webster Hardness Tester (also known as the clamp-type hardness tester) is a lightweight, on-site instrument that can quickly test the hardness of aluminum alloys. The test is rapid, simple, and one card can be used. The hardness value can be read directly. It conforms to the China Nonferrous Metals Standard YS/T420 and American Standard ASTM B647. It is one of the two instruments recommended by the standard YS/T420.
