Cylindrical Spherical Outside And Inside Surface Portable Hardness
Tester. Metal Durometer Hardness Tester Portable
Main Advantages
- Large screen (128×64 dot matrix LCD), showing all functions and
parameters.
- Can test at any direction
- Big measuring range. It can measure the hardness of all
metallic materials. Direct display of hardness scales Covered
common scales (HV, HB, HRC, HRB, HRA, HS).
- Seven impact devices are available for special application.
Automatically identify the type of impact devices.
- Big 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 value limit can be preset. It will alarm
automatically when the result value exceeding the limit.
- Battery indicates the rest capacity of the battery and the
charge status.
- User calibration function for special material calibration.
- Auto power off function
- Excellent after-sale service system for high quality products---two
years’ guarantee and all life maintenance. Easy to buy and
comfortable to use.
- Hermetically sealed metal shell, solid and durable, has excellent
resistance to vibration, shock and electromagnetic interference
ability.
- With USB or RS232 interface, convenient to connect with PC.
- Printer can be separated from main unit and copies of testing
result can be printed as required.
- Narrow testing space needed.
- 14 kinds of supporting rings for shaped material testing, such
as Cylindrical & Spherical Outside And Inside
Surface
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.
