Porous material pore size analyzerIt is one of the important properties of porous materials, which has a significant impact on a series of other properties such as permeability, permeation rate, filtration performance, etc. Therefore, the following should be noted when using it:
Precautions for using porous material pore size analyzer:
1. The compressed air pressure should be maintained between 0.3-0.7MPa, and the air source should be as clean and dry as possible.
2. Before measurement, it is necessary to ensure that the measuring head, ring gauge, and product are clean.
3. Pay attention to your eyes when reading, as the scale line and buoy are at the same height.
4. The measuring instrument does not allow any leakage position.
5. When the measuring instrument is stopped for storage, the zero position knob and magnification knob should not be too loose or too tight. When the measuring head and calibration ring gauge are not in use, rust prevention measures should be taken.
6. Long term use should undergo periodic testing. If there is a change in the size of the calibration ring gauge, the actual size should be used as the basis for adjusting the instrument.
The above are the precautions required for using a porous material pore size analyzer.
