Description

The HR-150 Series Rockwell Hardness Testers are reliable and cost-effective benchtop hardness testing systems designed for general industrial hardness measurement applications.

Available in analogue, digital manual and electronic digital configurations, the HR-150 Series provides an ideal entry-level solution for manufacturers, workshops, heat treatment facilities, educational institutions and quality control laboratories requiring dependable Rockwell hardness testing.

These systems support HRA, HRB and HRC hardness scales and are suitable for testing hardened steel, alloy steel, tool steel, brass, bronze, aluminium alloys and other metallic materials commonly used throughout engineering and manufacturing industries.

The series includes:

• HR-150A – Analogue manual Rockwell hardness tester
• HR-150S – Digital manual Rockwell hardness tester
• HR-150DS – Electronic digital Rockwell hardness tester

The electronic HR-150DS model offers improved testing efficiency with electronic loading and higher display resolution, while the HR-150A and HR-150S provide simple and economical manual operation.

Designed with a compact benchtop footprint and industrial-grade construction, the HR-150 Series delivers reliable hardness verification for routine inspection and quality assurance applications.
