    Mitech MHBS-3000Z Touch Screen Automatic Tower Digital Display Brinell Hardness Tester, based on the mechanical principle of hard alloy indenter pressing into the sample surface to produce indentation, realizing the material hardness measurement by measuring the diameter of the indentation, The use of photoelectric sensor system to high magnification optical measurement, equipped with automatic turret device, high sensitivity touch screen operation interface, can achieve automatic loading and unloading of electronic, easy to operate, high detection efficiency. It can meet the hardness testing requirement for the quality control and qualified assessment of the workpiece sample. It is widely used in metal processing and manufacturing, various metal material’s failure analysis and other fields like colleges and research institutions. It’s to improve the work efficiency, product qualification rate, saving production costs necessary professional precision testing equipment.

    Function & application

    Metal processing industry quality control links

    Universities teaching and demonstration test

    The failure test of metal material

    The material hardness test of scientific research institutions

    Working Principle

    Hardness is not a simple physical quantity, but a reflection of the material elasticity, plasticity, strength and toughness .and hardness test is the most simple mechanical testing method to determine the metal material performance. Also one of the important means to judge the products quality.

    Brinell hardness test: Test force(F) is on the steel ball with certain diameter(D) , pressed on sample surface. After a period of time, cancel the force. The indentation diameter is get by measuring with  micrometer ocular,thus to calculate the average pressure(N/mm²).

    Working Conditions

    Working Temperature18℃~28℃;

    Relative Humidity:≤65%;

    Clean environment, no vibration

    No corrosive media around.

    Instrument Features

    Suitable for measuring the surface is more rough cast iron, steel and other non-homogeneous specimen Brinell hardness;

    The use of automatic closed-loop pressure sensor control system, can dynamically reflect the loading process load


    The automatic turret mechanism can realize the automatic switching function between the objective lens and the indenter

     and improve the detection efficiency.

    Using touch screen display interface, display operation integration, simple and intuitive, the technical requirements of the

     operator is not high;

    Modeling novel, strong structure, reliability and operability is high, intuitive, high test efficiency;

    Equipped with excellent performance of the carbide indenter, high hardness, wear resistance, good toughness, while high

     temperature, corrosion resistance, to ensure that the instrument measured standard, stable and reliable;

    Support Brinell, Rockwell, Vickers and other hardness standard conversion;

    Equipped with high-speed thermal printer, you can quickly print out the test data;

    Meet ISO6507, ISO6506, GB / T231, JJG150 and other relevant domestic and foreign standards.

    Operating Method and Attentions

    Instrument Maintenance

    l Each technical requirement of the instrument has already reached the national standards before leaving factory. But its

     disassembly, transportation or voltage after delivery might cause some data in the instrument changed. So to make the

     electronic component in normal operation to reduce the testing error, you can use test force of 29400N(3000kgf) pressing

     times before starting the instrument to eliminate the instrument deformation.

    l The anti-interference component has been installed in the circuit to ensure the transmission of the loading or unloading

     single of the test force at all levels. At the same time, make sure no strong interference source around when using the

     instrument, and power off the instrument after finished the testing.

    l All the screws and the caps have been fasten tightly before the instrument leaving factory. However, the screw and cap

     may become less crowded because that the screw lever for loading and unloading are rotating all the time. If there is

     irregular noise, when the screw lever rotating, please check and tightened the screw and cap as the below figure shown.


    Pulley and cap

    l If there is some tiny noise when unloading, it is normal and no need to worry.

    l Hardness of the use of a period of one year, two adjacent indentation or indentation center to the edge of the distance of

     not less than 3mm, too close will affect the measured results;

    l The instrument screw level and other movable surface should be lubricated regular

    l When not in use for a long time, please cover the dust cover to prevent dust into the instrument interior. And

     the hardness block, indenter should be coated with antirust oil to prevent rusting after using.

    l Start using again after long time idling, please make testing after preheating the electrical components.

    l The accuracy of the reading microscope has been adjusted before leaving factory. It is prohibited to disassembly without

     authorization. Otherwise, it will reduce the reading accuracy of the micro eyepiece.

    l The storage and using of the reading microscope should avoid dust, damp and corrosive gas environment;

    l If there is dirt on the surface of the reading microscope lens, please wipe it with soft absorbent cotton or lens paper. If

     there is oil pollution, please wipe it slightly by the absorbent cotton with industrial alcohol or ether.

    l Don’t disassemble the instrument without authorization, maintenance related matter, please contact MITECH after-sale

     service department with 4000600280.
