Portable Rockwell Hardness Tester – C-Clamp Type QHR-CC-Series

Portable Rockwell Hardness Tester – C-Clamp Type QHR-CC Series is an enhanced version of a portable Rockwell hardness tester, featuring a C-shaped frame, screw arbor, and test head. It is designed to test both flat and curved parts, provided they can be securely clamped and the test surface is aligned with the test head. This model is convenient for measuring larger workpieces while maintaining the portability of a smaller hardness tester.

Portable Rockwell Hardness Tester – C-Clamp Type QHR-CC-Series Features

Double Drum Reading. The C-type Rockwell hardness tester features a double-drum reading mechanism that enhances accuracy by minimizing reading errors.

C-frame Structure. This model uses a clamping method to secure the workpiece before measurement, ensuring that the surface being tested is perpendicular to the indenter for stable and reliable results.

International Standards. This tester delivers precise measurements on par with desktop models, adhering to the standards set by ISO 6508, ASTM E18, and ASTM E110.
