Full Automatic Micro Vickers Hardness Tester AHVD-1000XYZ

Product Detail

AHVD-1000XYZ fully-automatic digital Micro hardness test 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 the Micro Vickers hardness test system, the computer control 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.

Other function: Free setting initial point, automatic reset, mechanical limit, etc. This system can meet different requirements of customers.

 

4. Multiple working stage application mode

Software can provide various programmatic sample test method via the combination of hardness tester control, automatic working stage control, digital imaging and manual / automatic reading.

 

5. Function powerful coordinates setting of automatic working stage

A variety of setting modes ensure the user still can get a satisfactory measurement result when sample place not in vertical or horizontal.

Two Points Mode: Click any two points on the test piece, then working stage (working table)  will move as its direction.

Normal Line Mode: select tangent to the edge of the specimen, then the working stage will move based on this direction;

Angle Bisector Mode: Via choose the angle degree, then working stage (working table) will move as the direction of angle bisector.

C. High resolution digital imaging technology

Adopt high resolution digital imaging technology, the highest resolution can reach1.3million pixel  (1280x1024),far more than general simulation camera resolution(less than 400,000 pixel ),provide base of high precision measurement.

Plug and play, with electric plug USB2.0 interface, make the installment and maintenance convenient, don’t need to close computer power, then can finish all installment, debugging and maintenance .

 

D. Unique advanced measurement technology, guarantee the high accuracy and repeatability of measurement.

1) Convenient scaling function—Use standard test card, conveniently calibrate the whole system.

2) Advanced data read technology—Not only get result of subpixel, high accuracy and repeatability.

3) Unique manual pick, homing point technology –User can pick roughly 4 peaks near the indentation, the system will judge automatically the best peak position, read directly, not only meet the general user’s habit, but bring down user’s labour intensity.

4) General manual test method—including 4 peaks measurement, 2 measured diagonally and so on. During 4 peaks measurement, can choose 4 peaks according random order, convenient users.




E. Perfect result processing, storage and output function

1) Hardness conversion

According to National standard,convert a variety of hardness value

Automatically, real time display.

2) Hardness –depth curve

According to test data, can draw up depth curve, and can choose many curves display merged, display lonely and multiple models.

3) Complete test parameters and result record.

Keep all test data result, combine with image storage, can storage measurement data, including D1,D2,HV value, Platform position X,Y and test force, load time,

Experiment method , calibration coefficient and test parameter.

4) Variety record method

Can choose WORD,EXCEL, special format etc variety file format.

5) Fixed rate to fix.

According to user’s requirement, can print material surface according to the set ratio.
