Electric Analog Rockwell Hardness Tester GL-HRD-150 for Alloy & Cast Iron QC

The GL-HRD-150 electric analog Rockwell hardness tester is designed for precision, repeatability, and ease of use in both laboratory and production environments. Featuring automatic loading and unloading of test force, it eliminates common manual errors, ensuring consistent and accurate results.

Dial Direct Reading – The large, high-contrast analog dial allows quick and clear readings, with only a simple zero-point adjustment required before testing.
Variable Load Selection – Test forces are changed by rotating the variable load handwheel, covering common Rockwell scales for a wide range of materials.
High Sensitivity & Stability – The rigid frame construction and precise force application deliver stable measurements over long-term use.

Specifications:

• Rockwell Scales: HRA, HRB, HRC
• Test Forces: 588 N (60 kgf), 981 N (100 kgf), 1471 N (150 kgf)
• Standards: ISO 6508-2, ASTM E18 compliant

Applications: Ideal for hardness determination of hard alloys, carburized copper, quenched copper, hard and malleable cast iron, as well as aluminum and copper alloys.

Why Choose GL-HRD-150: This bench-top Rockwell hardness tester offers fast operation, minimal operator influence, and reliable results—perfect for quality control in metallurgy labs, heat treatment facilities, and manufacturing lines.
