Universal Hardness Tester has Rockwell,Superficial Rockwell, Vickers and Brinell testing capability.

HBRVD-250 Digital Brinell Rockwell & Vickers Hardness Tester with a novel and beautiful appearance, multi functions, easy operation, clear and direct display, stable performance. It’s high-tech and new designed model, combining the mechanic, electric and optical features. This multi-function hardness tester with Brinell, Rockwell, Vickers 3 testing methods, as well as 7 steps test force can meet diverse test requirement.

Features:

3.1,The optical system designed by senior optical engineer not only has clear image, but also can be used as a simple microscope. The brightness is adjustable, the vision is comfortable, and it is not easy to be tired after long-time operation

3.2,The 7-inch LCD touch screen can visually display the hardness value, converted hardness, test method, test force, brightness, load holding time, measurement times, statistical data, test time and other test processes;

3.3,The system has its own calibration function, which can manually adjust the input error to calibrate the instrument;

3.4,When testing the surface, it is automatically corrected according to the standard surface radius;

3.5,Optical system brightness adjustable range: 0-100;

3.6, It can store 100 groups of test data, view the test data at any time, delete the current data or clear all test data;

3.7,The test force unit can be manually selected for mutual conversion, and the conversion unit is: (KGF, n)

3.8, It can display: maximum value, minimum value, average value, test times and test block name at the same time (the test block number can be entered);

3.9,The main interface can display 4 Conversion scales at the same time, and can switch: National Standard (GB), American Standard (ASTM) and international (ISO) standards. A total of 21 measurement scales can be converted: HRA, HRB, HRC, HRD, HRE, HRF, HRG, Hrk, hr15n, hr30n, hr15t, hr30t, hr45t, HK, HBW, HS, HBS, HV, RM (tensile strength) and MPa (pressure);

3.10, With diagonal length memory function, diagonal length is automatically memorized after power off, and measured directly after power on without secondary reset.

3.11, The upper and lower limit measurement range can be set and displayed on the main measurement interface, and the unqualified value will automatically prompt the alarm;

3.12, The operating system has 13 languages, which can be switched freely: Chinese, English, Russian, German, French, Spanish, Portuguese, Turkish, Czech, Japanese, Korean, Thai and Vietnamese;

3.13, With Brinell, Rockwell and Vickers test methods and eight levels of test force, it can meet a variety of hardness test requirements;

3.14, The built-in printer is configured, and the test data can also be output to USB flash disk for saving and analysis;

3.15. The casting shell is formed at one time, the structure is stable and does not deform, the pure white car baking paint has high grade, strong scratch resistance, and is still bright as new after many years of use;

3.16. Our company has the ability of self-development, design and production. Our machines provide lifelong parts replacement, maintenance and upgrading services;

Main application: 

4.1. Determination of Brinell, Vickers and Rockwell hardness of ferrous metals, non-ferrous metals and cemented carbides:

4.2. Brinell hardness of castings, annealed steel, normalized steel, non-ferrous metals and soft alloys;

4.3. Rockwell hardness of quenched, Quenched and tempered materials;

4.4. Vickers hardness of nitrided layer, ceramics, thin plate, metal sheet, electrodeposited coating and micro parts;
