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:
HL=1000X(Vb/Va)
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.

Cover all features and functions of traditional models:
►6 exchangeable hardness scales (HRB/HRC/HV/HB/HS/HL),measurable for the hardness strength σb;
►6 selectable impact devices(D/C/G/DC/DL/D+15) available for special usage, automatically identify the type of impact devices;
►8 kinds of material available, suitable to measure the hardness of all metallic materials.
Exclusive Features:
►Colorful Display: Colorful High-definition IPS Screen, with 2.4inch QVGA (320*240 dot matrix);
►Multilingual:Support many foreign language,including English,French,Italian,Japanese,etc.,can add other languages according to request;
►Multi-Scales Displaying Interface: Simultaneously display three impact values for three different and frequently-used hardness scales-HRC,HV,HLD, meeting requirements of multi-scales displaying without conversion, which is more convenient for users;
►Intuitive Curve Displaying Interface: The intuitive curve is formed by the impact values for the latest ten times tests, which enables to have a better and clear observation to the uniformity of workpieces;
►Mass Storage, Intuitive Testing Results: Store up to 11000 groups of testing values, each group includes 1-8 impact values and one average value which shows three different hardness scales at the same time, besides the present group shows MAX and MIN values and maximal error, the storage data interface is so intuitive and easy to read that it brings much more convenient to the users on data analysis;
►Bond Font Displaying Interface: Testing Values display in large and clear Font, which brings you legible and striking reading feelings.
