The cleanliness extraction equipment adopts a precision microporous filter membrane to vacuum and filter the fluid to be measured, intercepts the particulate pollutants in the fluid on the surface of the filter membrane, and then uses color scale colorimetry, paired weighing method, microscope observation method, instrument analysis and other methods to analyze the size, quantity and composition of particulate pollutants contained in the fluid. According to the nature of the fluid, particle size and analysis purpose, filter membranes with different properties and pore sizes are selected.
