Technical Specifications:
Models:
- 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.
- 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.
Features:
- Indenter: Re-engineered 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 abrasion 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.
