DTEC DH200 Portable Leeb Hardness Tester Best Quality with CE ISO ROHS Authorized Best-selling Model

DH200 Portable Hardness Tester is an advanced and innovative metal hardness testing instrument, which has many functions such as nice appearance,easy-operated,integrated design,high resolution display,low operation temperature and high accuracy,etc. 
It is applicable to big workpiece on-site hardness testing and batch testing on the workpiece in production lines. 
Moreover, it is also used in metal manufacturing industry, transportation,Power station, petrochemical industry,aircraft industry,construction and 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)




Main Application:

• 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

• 6 selectable impact devices(D/C/G/DC/DL/D+15) available for special usage, automatically identify the type of impact devices;

• 6 exchangeable hardness scales (HRB/HRC/HV/HB/HS/HL),measurable for the hardness strength σb;

• 10 kinds of material available, suitable to measure the hardness of all metallic materials;

• 100 groups storage capacity, including 0-7 measured value, average value, testing data, impact direction, impact times, material and hardness scale etc.;

• High contrast segment liquid crystal display, displaying figures, with EL background light;

• With standard data processing software and USB cable, enable to connect to PC and make further data analysis;

• Optional blue tooth function and wireless thermal mini printer with blue tooth, enable to print testing result on-site;

• Nice and attractive plastic case, coming with rubber sheath, suitable for use under poor working conditions;

• High accuracy in any impact direction (360°), automatically identify impact direction as well as impact device type and gravity compensation;

• Excellent after-sale service system for high quality products,easy to buy and convenient to use.
