Rockwell Hardness Meter

Product Introduction

The Rockwell Hardness Meter is a precision instrument used for quick and reliable measurement of the hardness of metallic materials. Based on the Rockwell hardness testing method, this device measures the depth of penetration of an indenter under a specified load, making it ideal for both quality control and production environments.

Widely used in metallurgy, automotive, aerospace, manufacturing, and laboratories, the Rockwell tester is suitable for both soft and hard metals, including steel, aluminum, copper alloys, and more. With options for manual, digital, and automatic models, it delivers consistent and accurate hardness readings across various Rockwell scales such as HRC, HRB, HRA, and others.

HR-150 Rockwell hardness meter is a hardness testing instrument with pure mechanical structure. This instrument is one of the most commonly used models of Rockwell hardness meter.

This instrument is very stable and reliable,  can be seen in factories, colleges and universities and research institutes.

The machine has accurate data, reliable and durable products, and high testing efficiency;

The dial can  read the HRA, HRB, and HRC scales directly;

It adopts precision hydraulic buffer, and the loading speed is adjustable;

Pure mechanical manual testing process, no electrical control required;

Widely applicable to quality monitoring in production sites, strong adaptability to the working environment;

Accuracy  meet GB/T230.2 ISO 6508-2 and US ASTM E18.
