Model SRWH-20 series, SRWH-B75 series, SRWH-BB75 series and SRWH-B92 Webster Hardness Tester

INTRODUCTION
A  portable instrument which can perform on-site hardness test on aluminum alloys. The test result can be got with only a simple clamp. It is convenient, efficient and reliable.
Webster hardness tester is the preferred instrument for testing aluminum alloys mechanical performance in accordance with American standard ASTM B647.
Used for quick test the hardness of aluminium profiles, tubings, sheets, accessories and other soft metal. Especially suitable for quick, non-destructive on-site 100% final products qualification test.
Webster hardness tester can be also used for testing hardness of copper, brass and soft steel.
