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
times32~1 ) 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.
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.
