benchtopfor non-ferrous metalsdigital display

Product overview
The HRS-150S digital Rockwell hardness tester is an automated precision testing instrument. Its electric loading/unloading mechanism and color touchscreen control suit laboratory and production environments that require stable, repeatable hardness measurements. The instrument integrates data processing and multi-standard hardness conversion functions to support quality management workflows.

Product advantages

• Automated closed-loop testing for repeatable operation and simple workflow integration.
• Coverage of multiple Rockwell scales and multi-standard conversion to address diverse testing requirements.
• Dual operation via a large touchscreen and physical buttons for flexible and reliable control.
• Built-in data management, printing and statistical functions to support inspection and traceability.
