Main functions and features of the instrument

1. The 7-inch LCD touch screen can directly display the hardness value, convert the hardness, test method, test force, brightness, initial test force retention time, total test force retention time, elastic recovery time, measurement times, statistical data, test time Wait for the test process to be intuitive and clear;

2. The system comes with a calibration function, which can automatically adjust the error range of 80-120%, or calibrate the instrument separately for low and high values

3. When testing the curved surface, it is automatically corrected according to the standard curved surface radius;

4. 100 sets of test data can be stored, and the test data can be viewed at any time, and the current data can also be deleted or all the test data can be cleared;

5. The test force units can be converted mutually, the conversion unit is: (Kgf, N)

6. Simultaneous display: maximum value, minimum value, average value, test times, product name;

7. 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 20 measuring scales can be converted: HRA, HRB, HRC, HRD, HRE, HRF, HRG, HRK, HR15N, HR30N, HR45N, HR15T, HR30T, HR45T, HK, HBW, HS, HBS, HV, Rm (tensile strength),

8. The screen sleep time can be set, and it will automatically enter the sleep state if it is not operated for a long time, saving environmental protection;

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

10. There are 14 languages in the operating system, which can be switched at will: Chinese, Traditional Chinese, English, Russian, German, French, Spanish, Portuguese, Turkish, Czech, Japanese, Korean, Thai, Vietnamese;

11. Equipped with a built-in printer, test data can also be output to U disk via USB for storage and analysis;

12. The casting shell has a stable and non-deformed structure once formed, the pure white car paint has a high grade, strong scratch resistance, and it is still bright as new after many years of use;

13. Our company has the ability to develop, design and produce on its own. Our machines provide parts replacement and maintenance upgrade services for life;
