Portable Rockwell Hardness Tester

The Portable Rockwell Hardness Tester models PHR-1 and PHR-2 are designed to deliver precise Rockwell hardness measurements with the same accuracy as laboratory bench testers. Both models conform to ISO 6508 and ASTM E18 standards and are ideal for testing small parts such as standard hardware tools and cutter tools.

Small and Lightweight: The tester weighs only 0.8 kg, allowing for easy handheld use or operation from a base seat.

Simple Operation: Functions similarly to a micrometer, making it user-friendly.

Traceability: Ensures accurate and consistent measurements with traceable test forces and standard hardness blocks.
