Brief introduction So far, the contact angle on solids can be directly and accurately measure ( the company produced JC2000 contact angle measuring instrument can be measured ) , but the powder samples, due to fine particles , the surface is not smooth, can not be measured directly, only indirectly measurement. Existing two kinds of measurement methods for compression method and osmosis. Tablet method is to measure the contact angle required powder by a tabletting machine and compressed into tablets , and then measuring the contact angle measurements on solid ; permeation method is the inner diameter of the powder contained in a hollow tube of uniform compaction, by compacting the powder bed was measured in the liquid permeation speed in which the contact angle was measured . Penetration method requires a reference for the perfect wetting liquid ratio. Washburn equation provides us with a wetting contact angle measurement principle. Technical Specifications: Measurement Method : Washburn osmometry Measuring range : 0-330mbar Accuracy : 0.16mbar Temperature range: Quartz tube dimensions : diameter 10mm, inner diameter of 8mm / 6mm Host Dimension : 295X240X260mm Power : 220V, 20W
