Mitech products focus on user's experience.It is your wise choice.
Software calibration automatically.100 groups (impact times 32 ~ 1) hardness measurements, each set of data includes single testing value, average value, measurement date / time, impact direction, frequency, material, hardness, and other information.Real-time display the remaining battery power, charging progress is displayed while charging.High brightness EL back-light display for easy use in dimly environment.Automatic sleep and shutdown and other power-saving features
Integrated thermal printer with the instrument as a whole, and quiet operation, fast print speeds, you can print the test report on-site.Equipped with PC software (optional), with functions of measurements transmission , value storage management, statistical analysis of the measured value, the print report of measured value, batch setting instrument parameters , to meet the higher requirements of quality for activities and management.Small size, portable, , stable and reliable performance, suitable for harsh environment field operations, prevent from vibration, shock and electromagnetic interference.
The basic principle is to use an impact body of certain weight impacts against the testing surface under certain test force, then measure the impacting velocity and the rebounding velocity of the impact body respectively when the spherically test tip is located 1mm above the testing surface.
The calculation formula is as follows:
Where, HL—— Leeb hardness value
VB—— Rebounding velocity of the impact body
VA—— Impacting velocity of the impact body
Many models as follows:
|Type of Impact Device||Distance of center of the two indentations||Distance of center of the indentation to sample edge|
|Not less than (mm)||Not less than (mm)|
