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.


*Large screen(320*240 Color LCD), showing all functions and parameters.

*Test at any angle, even upside down.

*Support "forged steel (Steel)" material, when using the D/DC impact device test "forged" sample, can read HB value directly, without the need for manual checking table.

*Wide measuring range. It can measure the hardness of all metallic materials. Direct display of hardness scales HRB, HRC, *HRA, HV, HB, HS, HL and three types of strength values immediately.

*Seven impact devices are available for special application. Automatically identify the type of impact devices. Large capacity memory could store 600 groups (Relative to average times321 ) information including single measured value, mean value, testing data, impact direction, impact times, material and hardness scale etc.

*Upper and lower limit can be preset. It will alarm automatically when the result value exceeding the limit.

*Battery information indicates the rest capacity of the battery and the charge status.

*User calibration function.

*USB port with the PC humanity multi-functions data proceeding software.

*Original imported high speed thermal printer support the immediate printing function. It can save data permanently.

*NI-*MH rechargeable battery as the power source. Charge circuit integrated inside the instrument. Continuous working period of no less than 200 hours (EL off and no printing).

*Auto power off to save energy.

*Industrialized housing design, sturdy, compact, portable, high reliability, suitable for harsh operating environment, vibration, shock and electromagnetic interference.

*Excellent after-sale service system for high quality products---two years’ guarantee and all life maintenance. Easy to buy and comfortable to use.
