Features:
u LCD display of 128×64 matrix is used.
u Using the D high precision impact device
u Converts to all common hardness scales(HV ,HB,HRC,HRB,HRA,HS).
u English displaying and menu operating, the operation is easy and
convenient.
u Hermetically sealed metal shell, solid and durable, has excellent resistance to vibration, shock and electromagnetic interference ability.
u With USB2.0 interface, multiple communication modes are adopted to
meet customized requirements of various users.
u Equipped with a data processing software, through the USB interface, can exchange data with computer printing and parameter setting
u 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.
u Max 600 groups（impact times:32～1）of data can be stored at internal
non volatile data storage.
u 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
light.
u Test values software calibration function.
u 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.
u Printer be separated from main unit and copies of testing results can be
printed as required.
u Power is two of AA battery. Continuous working period: approx. 200 h
(no back light on).
u 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.
u Failure analysis of pressure vessel, steam turbo-generator set and other
equipment
u Narrow testing space where work piece installed
