ASTM D 724 Water Drop Angle Measurement Contact Angle Analyzer Contact Angle Tester

Product Description

Product Description

Overview:
Contact angle is the angle θ between the tangent line of the gas-liquid interface at the intersection of gas, liquid and solid phases, and the tangent line on the liquid side and the solid-liquid junction line.
The ZL-2823A basic contact angle meter uses the principle of optical imaging to measure the surface contact angle, wettability, surface energy and other properties of the sample by means of image profiling, which is extremely cost-effective and comprehensive, and can meet the conventional sample surface wettability measurement.

Application:
Contact angle measurement is used in a wide range of industries and has become an important instrument for assessing surface properties in areas such as mobile phone manufacturing, glass manufacturing, surface treatment, materials research, chemical and chemical engineering, semiconductor manufacturing, coatings and inks, electronic circuits, textiles and fibres, and medical and biological applications.
