It is specialized in detecting the contact angle and interfacial tension in the filter material pores, and then obtaining the infiltration of the material liquid to the filter media pores, while the traditional seat drop method is affected by the penetration of liquid droplets, and the measurement error is large and mainly measures the surface of the filter media. As we all know, the filtration accuracy and efficiency of filter media mainly depend on the diameter of the pore throat and the wettability of the material, so the test results of this instrument are more valuable.
