Digital Micro Vicker Hardness tester with Touch Screen:- 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, our this machine perfectly solved above problems and  applies to test metal structure, including small parts, thin plates, metal foil, high quality wire, thin hardened layer and electroplated coating, also can test non-metal materials like glass, jewel, ceramic and so on The test consists of two parts.

First, the diamond indenter is driven by a known force and press into the surface of the measured material.

Second, user measures the diagonal length of the indentation and inputs the data into the touch screen, then will calculate automatically HK and HV value according to the standard GB and ASTM.

Introduction & Features:

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, our 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 path can working in same time, no need switch optical path rod. Greatly extend the service life of the optical system, and make test more easy.

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.

Main purpose and application:

• Steel, nonferrous metals, tinsel, cemented carbide, sheet metal, metallographic structure.
• Carburization, nit riding and decarburization layer, surface hardening layer, galvanized coating, coating.
• Glass, chip and ceramic material

Fully-Automatic Digital Micro Hardness Tester AHVD-1000XYZ System integrated with latest professional technique (optical projection, mechanic shift, electric control, digital projection, image analysis, and computer process etc.).The computer can control hardness tester and automatic working stage via software, and indicate the indentation on the screen by digitization, then test the micro hardness of metal parts of non-metal material, plating, harden depth, coating thickness, film thickness, and the distance between two points by automatic reading or manual reading; meanwhile, it can take the picture of surface appearance of metal, and print in fixed ratio.This system breaks through the traditional test method, complete the full automatic, high accuracy, high repeatability test; it is the important equipment for analysis material.In this Micro Vickers hardness test system, the computer controls the hardness tester working and receiving the information of hardness tester via RS-232 port; Computer control the control box of working stage through RS232, and control box control working stage moving and receiving the information; The optical signal of indentation via digital camera will transfer indentation image to computer screen, then get the Vickers hardness value by manual or automatic reading.
