Product Desciption
Digital Precision Durometer Multi Hardness Tester
Application Fields:
- The bearings and other parts, heavy work-pieces, metal material, pressure vessel, failure analysis of turbine generator unit and equipment
- Mechanical or permanent assembly components have been installed, the test space is very narrow, requires the original record regular test results
- Large work-piece within a wide range of more rapid test measurement site
Optional Impact Device:
Measuring Conditions:
- The weight of measuring object ≥ 2kg.
- The thickness must be ≥ 10mm.
- The surface roughness must be ≤ 1.6μm.
Tips: If do not meet the above conditions, the measuring object should be laminated with steel substrate by coupling agents.
Special Supporting Ring ( use for different shape surface):
