Introduction: Water drop angle tester is used to measure the wettability of liquid to solids. The instrument can be widely used in petroleum and chemical industry by measuring the contact angle of liquid to solid, calculating and measuring the free energy of liquid, ie the adhesion of liquid to solid, tension and other indicators. In the fields of medicine, paper making, exhaustive materials, etc., for scientific research and teaching purposes, the contact angle meter series manufactured by our company provides different types of instruments according to the different needs of users. The water drop angle tester is a standard type instrument for measuring the solid contact angle (water drop angle), surface energy and the like, and the surface tension of the liquid. Using advanced optical video measurement technology, the images taken by high-precision industrial cameras are sent to computers for data processing. The functions are complete and the operation is very convenient. Meets ASTM D 724, ASTM D 5946, ISO 15969 and other standards. It is widely used in quality testing of laboratories in industrial and mining enterprises and scientific research in universities. Features: 1.
