The SPR-963 Leeb Hardness Tester is a portable, high-precision device designed for non-destructive hardness testing of metallic materials. Utilizing the dynamic Leeb rebound principle, it measures hardness across multiple scales (HRC, HRB, HB, HV, HS, HL) and is ideal for applications in manufacturing, quality control, and field inspections. Its compact design allows for testing in confined spaces and at any angle.
- Multi-Scale Conversion: Directly displays hardness values in HRC, HRB, HB, HV, HS, and HL.
- Compact & Portable: Palm-sized (130×76×32mm, 340g) for use in narrow spaces.
- Versatile Testing: Measures at any angle (including upside-down) on flat or curved surfaces (min. radius: 30mm).
- Data Storage: Stores up to 50 test results with impact direction, material, and scale.
- User Calibration: Recalibrate to maintain accuracy after prolonged use.
- PC Connectivity: Optional USB/RS-232 cable for data transfer and analysis.
- Auto Power Off: Conserves battery life after 3 minutes of inactivity.
