Furthermore, the data processing module can perform pre-processing such as filtering and calibration on the collected data to improve data accuracy and reliability. The display and storage module is equipped with a high-resolution display screen, which can display the measurement data and the final calculated rock hardness value in real time. The data can also be wirelessly transmitted to external devices such as computers and mobile terminals.
