Ultrasonic Hardness Tester SONOHARD™ SH-22A

Hardness Tester – Ideal for Narrow and Curved Surfaces

Designed for hardness testing of quenched and hardened materials, this instrument is particularly suitable for measuring components with narrow, curved, or difficult-to-access surfaces. It complies with the ASTM A1038-19 standard, excluding tensile-strength indication and conversion.

Key Features

1. Compact Probe

   • Features an approximately 8 mm diameter probe head, allowing measurements in confined spaces and on curved surfaces.

2. Exceptional Durability

   • Designed for 1 million or more measurements without the need for periodic replacement of parts, thanks to its Static Loading Method.

3. Rapid Measurement

   • Provides a hardness reading in approximately 2 seconds, helping reduce inspection time and improve productivity.

4. Virtually Invisible Indentation

   • Creates an indentation of approximately 0.1 mm, making it suitable for inspecting finished products with minimal surface marking.

5. Independent of Supporting Surface

   • Measurement results are not significantly influenced by the material supporting the workpiece, whether it is wood, iron, resin, or another material.

6. Measurement in Any Direction

   • The instrument can be used in any orientation, providing flexibility when inspecting components in different positions.

7. Adjustable Upper and Lower Limits

   • Set acceptable hardness ranges and receive an alarm when a measurement falls outside the specified limits.

8. Suitable for System Integration

   • An optional function allows the device to be integrated into automated or inline inspection systems for continuous measurement and testing.

9. ASTM A1038-19 Compliant

   • Meets the requirements of ASTM A1038-19, with the exception of tensile-strength display and conversion.
