Main functions and features of hardness tester:
1. This machine has the characteristics of high precision, high repeatability and stability, simple operation, convenience and practicality, and extremely high cost performance;
2. It has 11 levels of test force and can test a wider range;
3. Optional digital display micrometer eyepiece, which can directly display the hardness value with a light click without a computer;
4. The system has its own calibration function, which can manually adjust the input calibration instrument and calibrate the eyepiece magnification.
5. It can store up to 100 sets of test data, and the average value and number of times can be displayed on the main interface. The product name can also be set.
6. The stored data can be viewed and printed in real time, and the current test results and all test records can be directly printed.
7. The operating system has 14 languages, which can be switched at will: Chinese, Traditional Chinese, English, Russian, German, French, Spanish, Portuguese, Turkish, Czech, Japanese, Korean, Thai, Vietnamese;
8. The main interface can display 4 conversion scales at the same time, and can switch: national standard (GB), American standard (ASTM) and international (ISO) standard, a total of 30 units can be converted: HRA, HRB, HRC, HRD, HRF, HR15N, HR30N, HR45N, HR15T, HR30T, HR45T, HV, HK, HBW, HBS, HS, HV50, HV10, HV5, MPa, Rm, Rm(c), Rm(Cr), Rm(CrV), Rm(CrNi), Rm(CrMo), Rm(NiMo), Rm(MnSi), Rm(High ), Rm (STNL)
9. Equipped with high-performance stepper motor to automatically load and unload test force, the noise generated during the test is smaller
10. Using photoelectric sensing technology and microcomputer control system, it can automatically compensate, and the test results are accurate and stable;
11. Automatically input the indentation diameter and directly display the hardness value;
12. Self-designed high-magnification LED optical measurement, high image clarity, adjustable brightness, and long-term operation without fatigue;
13. The shell structure is stable and does not deform, and can work in relatively harsh environments;
14. The surface is treated with automotive paint technology, with strong scratch resistance, and it is still bright as new after many years of use
Main uses and scope of use:
1. Suitable for hardness test of metal materials with large grains, which can reflect the comprehensive performance of the material;
2. Cast iron, steel, non-ferrous metals, especially for softer metals, such as pure aluminum, lead, tin, etc.
3. Can be used for the determination of hardness test of certain non-metallic materials such as hard plastics and bakelite
