ASI Advanced Touch Screen Digital Micro Vickers Hardness Tester ASI-DV-1AT-8P

ASI Advanced Touch Screen Digital Micro Vickers Hardness Tester ASI-DV-1AT-8P

Main Features:

1.       One-time casting of a large test space machine body with car painting technology; the structure is more stable and the appearance more decent.

2.       Digital 10X eyepiece with built-in encoder: click the encoder, and the machine will automatically get indentation diagonal length data D1 & D2; no need to manually input data into the machine, greatly improving testing accuracy and working efficiency.

3.       With large touch screen digital display, directly display hardness value, dwell time, conversion hardness value, etc.

4.       Menu structure interface, easy operation.

5.       With HV/HK test function (if you need the HK test function, purchase the optional Knoop diamond indenter and standard Knoop hardness blocks).

6.       With the built-in printer, test results can be printed out directly.

7.       With the RS232 communication port, the machine can upgrade to the semi-automatic or fully automatic type easily if needed in the future.

8.       Double optical path design. Reserved photo camera pot; can add camera and work with hardness tester analysis and measuring software system

Main purpose and application:

1.       Steel, nonferrous metals, tinsel, cemented carbide, sheet metal, metallographic structure.

2.       Carburization, nitriding and decarburization layer, surface hardening layer, galvanized coating.

3.       Glass, chip and ceramic material
