HARDNESS TESTER

Multi-function Digital Macro Vickers Hardness Tester

MHVD-10AP-4.jpg

Equipped with imported high quality components ensure the multi-function digital Macro hardness tester can stable working for a very long time. The advanced data measuring and control system in conjunction with 5.6’ digital LCD screen (which can provide comprehensive data) to used for quality control. Easy operation (greatly improve the working efficiency) and decent appearance can meet the high requirement of customers.

 

Main functions and features:

1. Equipped with Omron brand digital eyepiece and Data computing systems which accuracy can reach to 0.01um; Just click one button the hardness value will display on screen directly .

2. With precise sensor (load cell), the test force more precise and test result more accuracy. Test force range more widely.

3. Main components adopted American 3M, Allegro, and Japanese Omron, NKK brand, ensure the instrument can stable working for a very long time.

4. The independent research and development of lift & down system and positioning system, ensured the accuracy and repeatedly of the testing process.

5. The optical system designed by our senior optical engineer not only meet the definition of hardness testing requirements, but also can observe the micro structure of the material, image is very clear.

6. According to different visual habits of the operators, the strength of the light source can be adjusted. To avoid the visual fatigue for long time operation.

7. With Vickers hardness and Knoop hardness testing capabilities. Automatic measuring the indentation diagonal length, the hardness and conversion hardness will show on the screen directly, no need to check hardness table.

8. Industrial digital screen can direct display hardness value, conversion hardness, testing method, testing force, dwell time, test number and testing process; The built-in printer can print testing times, hardness value, average value, Max. Value, Min. Value, Xmax-Xmin directly,  easy for operator to save the data.

9. Equipped with data transfer software, all the testing data can be transfer to computer via RS232 port, then can edit and save the data on computer.

10. One-time casting aluminum molding shell ensure structure more stable; Adopted car painting technology, pure white color looking more decent; High scratch resistance capability, used for years still brightness like new.

11. Factory directly supply, we have products develop &design & produce ability, all the parts provide life-time replacement and maintenance service.

 

 

Main purpose and application:

1. Steel, nonferrous metals, tinsel, cemented carbide, sheet metal, metallographic structure.

2. Carburization, nitriding and decarburization layer, surface hardening layer, galvanized coating, coating.

3. Glass, chip and ceramic material.
