Main Features:1. The optical system designed by our senior optical engineer not
only meet the definition of hardness testing requirements, but also
can observe the micro structure of the material, image is very
clear.
2. According to different visual habits of the operators, the
strength of the light source can be adjusted. To avoid the visual
fatigue for long time operation.
3. With Vickers hardness and Knoop hardness testing capabilities,
and testing range from HV0.2 to HV5. By measuring the indentation
diagonal length, the hardness will show on the screen directly, no
need to check hardness table.
4. Industrial digital screen can direct display hardness value,
conversion hardness, testing method, testing force, dwell time,
testing times and testing process;
5. Reserved CCD camera optical path, support machine work with
computer and hardness 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, coating.
3. Glass, chip and ceramic material.
