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. TECHNICAL PARAMETERS STANDARD ASSEMBLY OPTIONAL ACCESSORIES Testing Range: Resolution: Repeatability: Weight: Tester Standard hardness block Spare indenter Calibration wrench Small screwdriver Carrying case Dial assembly Indenter Standard hardness block Dial glass FEATURES • Indenter: Re-engineerred with advanced material and new production technology manufactured, higher hardness, long service life, good interchangeability. • Indicator Hand: High strength indicator hand, less likely to be bent by long-term using or mis-operation. • Dial Glass: High strength, high toughness, uneasy to be broken or scratched. • Handle: Forged aluminum alloy handle with fine anodized finishing, high resistance to abraision and stain. • Hardness Blocks: Tested by standard rockwell hardness tester, the hardness block are attached with test report. • Stability: Stable full scale point, stable calibration point, indicator never glides. • Conversion: Results can be converted to Vickers, Rockwell and Brinell. MODELS • W-20: the most popular model, used to test normal aluminum profiles. • W-20a: used to test aluminum profiles with thickness within 13 mm. • W-20b: used to test aluminum tubings with inner diameter over 6 mm. • W-B75: used to test brass tubings and brass sheets. • W-BB75: used to test copper tubings and copper sheets. • W-B92: used to test soft stainless steel sheets, cold-rolled steel, etc.
