Product Overview

LHBRV-187.5F Touchscreen Digital Display Brinell Hardness Tester

The touchscreen digital Brinell‑Rockwell‑Vickers hardness tester features a modern design, comprehensive functionality, user-friendly operation, and clear, intuitive display, while delivering stable performance. As a high‑tech, integrated opto‑mechatronic device, it supports Brinell, Rockwell, and Vickers testing methods and incorporates a versatile hardness scale with 23 measurement scales, meeting diverse hardness‑testing requirements. It offers high measurement accuracy, simple operation, excellent sensitivity, and convenient use, with stable readings. Equipped with a built-in printer, it can also be optionally connected to a computer via an RS‑232 data cable or export measurement reports to a USB flash drive. Its large LCD touchscreen provides a rich, easy‑to‑use interface.

Main uses and scope of application:
1. Determination of Brinell, Vickers, and Rockwell hardness for ferrous metals, nonferrous metals, and cemented carbides:
2. Brinell hardness of castings, annealed steel, normalized steel, nonferrous metals, and soft alloys;
3. Rockwell hardness of heat-treated materials such as quenched and tempered steels;
4. Vickers hardness of nitrided layers, ceramics, thin sheets, metal foils, electroplated coatings, and miniature components;

Key features:
1. The optical system designed by the optical engineer not only delivers crisp images but can also function as a simple microscope, with adjustable brightness, comfortable viewing, and reduced eye strain even during prolonged use.
2. The 7-inch LCD touch display provides a clear, intuitive view of hardness values, converted hardness scales, test methods, test force, brightness, dwell time, number of measurements, statistical data, and test duration, making the entire testing process easy to understand at a glance.
3. The system features a built-in calibration function, allowing manual adjustment of the input error to calibrate the instrument.
4. When testing curved surfaces, automatic correction is applied based on the standard surface radius.
5. Adjustable brightness range of the optical system: 0–100;
6. 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.
7. The test force unit can be manually selected and switched between: (Kgf, N).
8. Can simultaneously display: maximum value, minimum value, average value, number of tests, and test block name (test block number can be entered).
9. 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 21 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, Rm (tensile strength), and MPa (pressure).
10. Features a diagonal‑length memory function: the diagonal length is automatically saved after shutdown, and upon startup, measurements can be taken directly without needing to reset the zero point.
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 a total of 13 languages, which can be switched at will: Chinese, English, Russian, German, French, Spanish, Portuguese, Turkish, Czech, Japanese, Korean, Thai, and Vietnamese.
13. Equipped with Brinell, Rockwell, and Vickers testing methods and eight levels of test force, it can meet a wide range of hardness‑testing requirements.
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 die-cast aluminum housing features a one-piece molded structure that remains stable and deformation-free; its pure white automotive-grade baked finish boasts superior quality, excellent scratch resistance, and retains a like-new shine even after years of use.
16. Our company possesses in-house R&D, design, and manufacturing capabilities. We provide lifetime support for spare parts replacement and maintenance upgrades for our machines.
