Blaine Fineness Air Permeability Apparatus

Blaine Fineness Air Permeability Apparatus

Used to determine the particle size of Portland cement, limes and similar powders expressed in terms of their specific surface.
The user can adjust the porosity of the sample freely, and the measurement range is wide
Users can also adjust the speed of air pump according to the needs of measurement
fully automatic Cement Blaine Fineness Apparatus is a liquid crystal display, which is intuitive and convenient
Single chip microcomputer and integrated circuit are used to automatically adapt to different temperatures, automatically detect the working state of the instrument, and the measurement results are accurate.
Automatic detection of water level, automatic timing, automatic temperature measurement, automatic calculation and display results.
In addition to manual loading, the whole test process is completed automatically to avoid human error.
Press the measurement key once to get a measurement result.
