Product Description:
HV-1000 micro hardness tester is opto-mechatronics integration of high-tech products, the machine modelling is novel, uses computer software programming, optical measurement system, and has good reliability, operability and intuitive, is to use a new type of micro precision machinery technology and photoelectric technology Vickers and Knoop hardness test instrument.The microhardness is used to measure the hardness of thin materials and small parts, such as the parts in clocks, instruments and instruments, and the hardness and thickness of the coating, cementation layer and nitride layer. It is an important means to test the quality of products and make reasonable processing technology, especially one of the most commonly used methods in materials science and metallography.
Performance characteristics:
1, Hardness value display function: changed the traditional cumbersome manual measuring their look-up table after the results of calculation, and simply enter measurement in this machine indentation length of machine get the result automatically. Convenient, quick, intuitive, to save customer operation time.
2, This machine has automatic force change function: can according to customer need to select the corresponding force value size and read automatically test force, experiments don't have to manually input forces value, direct spinning load change the handwheel device of automatic real time read the corresponding experimental value.
3. This machine has dual explicit function: the machine adopts LCD screen, and can display two hardness results at the same time. The HRA, HRB, HRC, HB, and other hardness conversion results can be determined by using the operation control key.
Product features:
1. The test force is small and can be tested for thin samples or coatings.
2. The indentation is small, which can be considered as a nondestructive test, while multi-point test can be carried out in a minimum range.
3. New floating-point calculation method to make the test results more consistent with the theoretical results.
4. The whole new three-way optical path system is close to 100% full light absorption;
5. The integrated structure design of the objective lens (indenter) - base board - optical system - lighting is almost 100% perfect optical system.
6. The host hardware and software are set up with a reserved port, and some functions can be upgraded with easy dialing code, which makes the subsequent upgrade service easier.
7. Using high-end optical imaging technology, the image indentation is clear;
8. Precise 360 degree tower equalize technology to make tower positioning more accurate.
9. Adjustable loading and unloading system allows operators to perform multiple tests easily.
10. The lighting system can be 0~100% without level adjustment, which reduces the visual fatigue of the operator, while the automatic control of the lighting system can also complete the automatic shutdown and start-up.
11. The advanced storage system can remember test results at any time to avoid loss of data caused by power failure.
12. High-precision lifting shaft makes the machine run more smoothly and comfortable.
13. Stable mechanical structure design, making machine life longer.
