1:LCD display of 128×64 matrix is used.
2:Converts to all common hardness scales(HV ,HB,HRC,HRB,HRA,HS).
3:English displaying and menu operating, the operation is easy and convenient.
4:With USB interface, multiple communication modes are adopted to meet customized requirements of various users.
5: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.
6:Max 600 groups（impact times:32～1）of data can be stored at internal non volatile data storage.
7: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.
8:Back light display has been used to make convenient for the use in poor light.
9:Test values software calibration function.
10: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.
11:Printer be separated from main unit and copies of testing results can be printed as required.
12:Power is two of AA battery. Continuous working period: approx. 200 h (no back light on).
13: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.
