What is Contact Angle?
Contact angle is a quantitative measure of wetting of a solid by a liquid. It is defined geometrically as the angle formed by a liquid at the three phase boundary where a liquid, gas, and solid intersect.
How to test the value?
HUD-U805 CONTACT ANGLE GONIOMETER will be the best choice, which is used for measuring the contact angle of a liquid on a solid, which wettability of liquid on the solid, the instrument can measure the contact angle of various liquids of various materials. The instrument is for petroleum, printing and dyeing, pharmaceutical, paint, mineral processing industries such as scientific research.
