DTEC DH600 Portable Leeb Hardness Tester

DH600 Colorful Screen Hardness Tester is a state-of-the-art model with colorful high-definition, 2.4inch QVGA(320*240 dot matrix) IPS Screen and mass storage; what’s more, it has an exclusive function of multi-scales display(display HRC,HV,HLD at the same time on the screen),function of intuitive display curve interface.

It is applicable to big workpieces on-site hardness testing and batch testing on the workpieces in production lines. Moreover, it is also used in metal manufacturing industry, transportation, power station, petrochemical industry, aircraft industry, construction, lab, etc.

Working Principle:

When the impact body,with a certain weight,impacts against the specimen surface under the action of spring force,leeb hardness comes from the ratio of the impacting velocity(VA) and the rebounding velocity(VB) of the impact body by the moment the spherical testing tip is located at 1mm point from specimen surface.

With principle of electromagnetism,the permanent magnet in the coil of impact device produced an induced voltage, which is in proportion to the impact body velocity.

The leeb hardness values are calculated by the following formula:

Using Scopes:

Die cavity of molds.

Bearings and other parts.

Failure analysis of pressure vessel, steam generator and other equipment.

Heavy work piece.

The installed machinery and permanently assembled parts.

Testing surface of a small hollow space.

Material identification in the warehouse of metallic materials.

Rapid testing in large range and multi-measuring areas for large-scale work piece.
