Superficial Rockwell Hardness Tester

The Superficial Rockwell Hardness Tester includes models PHR-1S, PHR-2S, and PHR-1ST, designed for precision testing of small and thin materials. These testers adhere to the Rockwell hardness testing principles and offer reliable, real results. They are suitable for testing materials such as tinplate, thin steel plates, copper strips, aluminum strips, small stamping parts, and thin carburizing layers.

Non-destructive Testing: The small indentation does not affect the use of most parts, making it effectively non-destructive.

Small and Lightweight: With a minimum weight of 0.7 kg, these testers are versatile for both workshop and field use.

International Standards: Provides accuracy equivalent to desktop models, complying with ISO 6508, ASTM E18, and ASTM E110 standards.
