HRM-45SS Touchscreen Digital Display Surface Rockwell Hardness Tester

Description

Product Introduction:

The HRM‑45SS touchscreen digital surface Rockwell hardness tester is our company’s next‑generation, high‑tech product—multifunctional, highly accurate, and exceptionally stable. It features a modern, sleek design with an integrally cast housing that ensures superior stability. Its touchscreen interface is menu‑driven, offering simple, intuitive, and convenient operation. The measurement system employs a grating sensor and computer control, with hardness values displayed directly on the LCD screen, making it a fully electromechanical hardness testing instrument. It can automatically convert among various hardness scales and determine the minimum specimen thickness. When testing cylindrical specimens, it can automatically apply correction factors. A built‑in printer enables easy retrieval of test results. With automated operation, it eliminates human error in handling and reading measurements. Additionally, the unit is equipped with an emergency stop device for enhanced safety.

Main uses and scope of application:

Surface‑hardened steels, copper and aluminum alloy sheets, strip steel, cemented carbides, as well as galvanized, chromium‑plated, and tin‑plated materials—along with various metals undergoing surface heat treatment or chemical surface treatments—plus castings and forgings, and both flat and cylindrical workpieces. These are widely used in the steel, nonferrous metal, automotive, and aerospace industries. Cemented carbides, ceramics, stainless steels, and other materials are also covered. Due to its broad applicability, Rockwell hardness testing has become extensively adopted in manufacturing, serving as a key method for assessing product quality and optimizing machining processes. The Rockwell hardness tester is a standard instrument for hardness testing in production facilities, universities, and research institutions, as well as for educational and scientific research purposes.

Key functions and features:

1. The 7-inch LCD touch display provides a clear, intuitive view of hardness values, converted hardness scales, test methods, test forces, brightness, initial test force hold time, total test force hold time, elastic recovery time, number of measurements, statistical data, test duration, and other key parameters of the testing process.

2. The system features a built-in calibration function that can automatically adjust the error range to 80–120%, or perform separate calibrations for low and high values.

3. When testing curved surfaces, automatic correction is applied based on the standard surface radius.

4. It can store 100 sets of test data, allowing you to view the data at any time, as well as delete the current data or clear all test data.

5. The units of test force can be converted between each other; the conversion units are: (kgf, N).

6. Can simultaneously display: maximum value, minimum value, average value, number of tests, and product name.

7. The main interface can simultaneously display four conversion scales and allows switching among the following standards: Chinese National Standard (GB), American Standard (ASTM), and International Standard (ISO). A total of 20 measurement scales are supported for conversion, including HRA, HRB, HRC, HRD, HRE, HRF, HRG, HRK, HR15N, HR30N, HR45N, HR15T, HR30T, HR45T, HK, HBW, HS, HBS, HV, and Rm (tensile strength).

8. The screen timeout can be configured; after a prolonged period of inactivity, the device automatically enters sleep mode, saving energy and protecting the environment.

11. The upper and lower measurement limits can be set and displayed on the main measurement screen; non‑conforming values trigger an automatic alarm.

12. The operating system supports 14 languages, which can be switched at will: Chinese, Traditional Chinese, English, Russian, German, French, Spanish, Portuguese, Turkish, Czech, Japanese, Korean, Thai, and Vietnamese.

14. Equipped with a built-in printer; test data can also be exported via USB to a USB flash drive for storage and analysis.

15. The cast housing features a one-piece, integral structure that remains stable and deformation-free; its pure white automotive baked finish exudes high quality, offers excellent scratch resistance, and retains a like-new shine even after years of use.

16. Our company possesses the capability for independent research, development, design, and manufacturing. We provide lifetime support for spare parts replacement and maintenance upgrades.
