*The assembled machinery and permanently installed parts
*Die cavity of molds
*Heavy work piece
*Bearings and other parts
*Cases which require the test result with normalized original recording
*Material identification of the metal material warehouse
*Quick tests of large range and multipoint measuring positions for heavy
*LCD display of 128×64 matrix is used.
*Using the D high precision impact device
*Converts to all common hardness scales(HV ,HB,HRC,HRB,HRA,HS).
*English displaying and menu operating, the operation is easy and convenient.
*Hermetically sealed metal shell, solid and durable, has excellent resistance to vibration, shock and electromagnetic interference ability.
*With USB2.0 interface, multiple communication modes are adopted to meet customized requirements of various users.
*Equipped with a data processing software, through the USB interface, can exchange data with computer printing and parameter setting
*Equipped with 7 types of impact devices which need not to be recalibrated when changing them, the system can identify the type of impact device automatically.
*Max 600 groups（impact times:32～1）of data can be stored at internal Non-volatile data storage.
*Upper and lower limit of hardness can be preset; When the tested value exceeds the limits, alarm will send out automatically to make convenient for the requirements of batch measurements.
*Back light display has been used to make convenient for the use in poor
*Test values software calibration function.
*Material of “cast steel” is added; HB values can be read out directly when D/DC impact device is used to measure “cast steel” work piece.
*Printer be separated from main unit and copies of testing results can be printed as required.
*Power is two of AA battery. Continuous working period: approx. 200 h
(no back light on).
*Software of PC can be installed according to the requirements of user,
the function will be more powerful to satisfy the more strict demands of quality control and management.
