- Indenter: Re-engineered with advanced material and new production technology manufactured, higher hardness, long service life, good interchangeability.
- Indicator Hand: High strength indicator hard, less likely to be bent by long-term using or misoperation.
- 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.
- W-20: the most popular model, used to test normal aluminum profiles.
- W-20a: used to test aluminum profiles with thickness within 13mm.
- W-20b: used to test aluminum tubings with inner diameter over 6mm.
- 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.
