Product Overview
The LS256 ultrasonic hardness tester uses the ultrasonic contact impedance method for hardness testing and can measure the hardness of a variety of metal materials. Due to its minimal indentation, it causes little damage to the surface of the sample being tested, making it suitable for measuring the hardness of metal coatings, platings, and hardened layers. It comes with multiple built-in hardness scales, allowing conversion between Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS), Rockwell (HRA), Rockwell (HRB), and Rockwell (HRC).
Product Features
1. Uses the Ultrasonic Contact Impedance (UCI) method, with minimal indentation for non-destructive testing.
2. Equipped with dual probes, flexibly meeting hardness testing needs for ultra-thin, special-shaped components, and confined spaces.
3. Integrated design, compact and lightweight, easy to carry, suitable for rapid on-site inspection.
4. Supports free switching between multiple hardness scales such as HV, HRC, HRB, and HB, eliminating the need for manual conversion or table lookup.
5. No complex setup required; ready for use upon power-on, completing measurement and displaying results in just 1 second.
6. High measurement accuracy, ensured to pass reliable metrology institute testing.
7. Features user calibration function, allowing self-calibration using standard hardness blocks.
8. The instrument connects to a mobile app via Bluetooth, enabling multi-group data storage and measurement data sharing.
9. When used with a testing stand, it achieves higher measurement accuracy and better repeatability.
Working Principle
The LS256 ultrasonic hardness tester uses the ultrasonic contact impedance method for hardness testing.
Application Areas
Metal coatings, platings, and hardened layers
Operation steps
1. Ready to use upon startup, no complex setup required.
2. Select the appropriate probe according to the testing requirements.
3. Make contact between the probe and the surface of the sample being tested.
4. Wait 1 second to obtain the measurement result.
5. Data can be stored and shared via Bluetooth connection to a mobile device application.
6. If calibration is needed, perform self-calibration using a standard hardness block.
Precautions
- Ensure good contact between the probe and the sample surface during measurement.
- Suitable for micro-indentation measurement of metal coatings, platings, and hardened layers.
- Ready to use upon startup, no complex setup required.
- High measurement accuracy, but regular calibration with standard hardness blocks is necessary to maintain precision.
- Using a test stand can improve accuracy and repeatability.
