HR-150DS Electric Digital Display Rockwell Hardness Tester

Description

Product Introduction:

The HR-150DS electric digital Rockwell hardness tester features an automatic loading/unloading mechanism, with test force adjustment achieved by rotating the load‑change handwheel. It is easy and quick to operate, requires no dial zeroing, and provides direct digital readouts, eliminating human‑induced measurement errors. With high sensitivity and excellent stability, it is well suited for both workshop and laboratory use and has found widespread application across numerous industries.

Main uses and scope of application:

Quenched steel, tempered steel, annealed steel, bearing steel, strip steel, hardened thin steel sheets, and cemented carbides are widely used; accordingly, Rockwell hardness testing has found extensive application in manufacturing, serving as a primary method for assessing product quality and establishing appropriate processing parameters. The Rockwell hardness tester is a commonly employed instrument in production facilities, universities, and research institutions for conducting hardness tests and supporting teaching and research activities.

Key functions and features:

1. The hardness value is displayed directly on the digital display, with a resolution of 0.1; the measured results exceed the national standard.

2. Direct conversion between HV and HB hardness units is supported.

3. Low power consumption and long operating life; the digital display is powered by a CR2450 battery.

4. Features a time display;

5. Equipped with a data output function, it can be connected to a computer or linked to a miniature printer.

6. The housing is manufactured in a single casting using a specialized sand‑casting process, ensuring a stable, deformation‑free structure that can operate reliably even in harsh environments. It features high‑grade automotive paint with excellent scratch resistance, maintaining a like‑new shine even after years of use.

7. Test force: Application, hold, and release are performed automatically;

8. We possess in-house R&D, design, and manufacturing capabilities, and our machines come with lifetime support for parts replacement, maintenance, and upgrades.
