Product Description
The JH-150HR High Precision Rockwell Hardness Tester is a classic mechanical model designed for stable and accurate hardness measurement.
It operates with a manual loading system, requiring no external power supply, providing consistent and precise test-force control.
The high-sensitivity dial indicator enables direct and reliable hardness readings with minimal operator influence.
The main frame is made by a one-piece casting process, ensuring long-term dimensional stability and high mechanical strength.
The outer surface adopts an automotive-grade baked enamel finish, which is scratch-resistant, corrosion-proof, and maintains gloss after years of use.
This instrument is suitable for a wide range of metallic materials and is ideal for industrial inspection, tool manufacturing, and educational laboratories.
Fully compliant with ASTM E18, ISO 6508, and EN 10109 international standards.
