EBP - Model DV-1AT-8P -LCD Screen Digital Microhardness Tester With Hardness Conversion Function
The traditional Micro hardness tester has poor precision and can barely meet the needs of visual observation & measurement. If connect with camera and software, the indentation image of traditional Micro hardness tester always out of central position. It is very big problem of measuring and analysis process. Fortunately, this machine perfectly solved above problems.
1) Guided by optical cross rails to ensure high guiding accuracy;
2) Fast and smooth force transmission can be achieved by using the secondary transmission force of the rack and pinion.
3) This machine equipped with most advanced High transmission ratio high precision worm gear rod, can achieve stable continuous lifting, and greatly improved the accuracy and repeatedly of the testing process. This update is very important to improve working performance and working efficiency.
4) Equipped with dual optical path, one optical path for eyepiece
system, another path for CCD camera, both paths can work in same time, no need switch optical path rod. Greatly extend the service life of the optical system, it and make test much easier.
5) Adopted 8’’ touch screen, menu structure, and digital eyepiece with built-in encoder, just click button on encoder, the diagonal length of indentation D1, D2 and hardness value will display on touch screen directly, very easy operate.
6) With hardness conversion function, from HV can convert to HRA, HRB, HRC, HBW, etc. scales.
7) With (HV & HK) Vickers and Knoop hardness testing capabilities.
8) OK/NG judgement function.
9) Both lens (10X & 40X) can used for measurement, suitable to test widely hardness range of materials from most soft to very hard.
10) Equipped with data transfer software, test data can save to computer and generate test report automatically in word format.
