Product Overview

The HR-45A Surface Rockwell Hardness Tester applies a smaller testing force and is used to test fine, small, thin samples that cannot be tested by regular Rockwell hardness testers, as well as components with surface hardening layers and those requiring minimal indentation.

Product Introduction

1. Utilizes mechanical manual testing, requiring no power source, offers wide applicability, ease of operation, and demonstrates good cost-effectiveness and practicality.

2. The body is made of high-quality cast iron, created in a single casting, and finished with an automotive paint process, resulting in an attractive and sleek appearance.

3. The dial directly reads hardness values and can optionally accommodate other Rockwell scales.

4. Incorporates a frictionless main spindle for high testing force accuracy.

5. Includes a precision-cast hydraulic buffer without fluid leakage, ensuring smooth load and unload operations without impact, along with adjustable speed.

6. Accuracy complies with GB/T230.2, ISO 6508-2, and the American ASTM E18 standards.

Scope Of Application 

1. Surface-hardened steel, copper, aluminum alloy sheet, steel strip, hard alloy steel, galvanized, chromium-plated, tin-plated materials.

2. Various metal materials subjected to surface heat treatment and chemical surface treatment.
