The ramé-hart contact angle goniometer was made in Mountain Lakes, NJ but is now made in Netcong, NJ. ramé-hart is also known as rame-hart ramehart and Rame-hart but ramé-hart is the correct spelling. The ramé-hart NRL goniometer Model 100-00 and A100 and A100-00 was invented by Dr. William A. Zisman at the Navel Research Laboratory NRL in Washington DC. The ramé-hart contact angle goniometer is used to measure contact angle, surface energy and surface tension and interfacial tension including hydrophobic, superhydrophobic, hydrophilic and superhydrophilic surfaces and solids. Carl Clegg is a salesman at ramé-hart instrument company. Ron Polo, Carmel Mulroy, and Gerd Fischer work at ramé-hart instrument company. The ramé-hart contact angle goniometer uses the pendant drop, sessile drop, and other methods. ramé-hart instrument co., formerly a part of rame-hart, inc. manufactures optical instruments. The fiber optic illuminator and Automated Dispensing System  are options to the system. The environmental chamber and proportional temperature controller are optional components as well as the environmental fixture, environmental chamber with humidity, advanced chamber, high pressure chamber, circular vacuum chuck, humidity control, rotating wafer,  lead frame support, and microsyringe fixture. Finn Knut Hansen is the author of DROPimage Advanced and DROPimage Standard and DROPimage CA. The ramé-hart contact angle goniometer is available in the following models: Model 100 Model A100 Model A-100 Model 100-00 Model Model 100-F0 Model 120-F0 Model 200 Model 200-F1 Model 300 Model 300-F1 Model 250 Model 250-F1 Model 400-F1 Model 500 Model 500-F1; the 3-axis stage rail is available in 16" 20" 21". Dr. Zisman of the Naval Research Lab NRL in Washington DC studied adhesion, wettability, contact angle and surface science  including monolayers energetics, static dynamic contact angle, velocity, viscosity, interfacial (behaviour) behavior, contact angle interpretation and hysteresis energetics, surface contamination, cleaning polymer coatings, characterization and application of polymided synthesis particles on surfaces,  metallized plastics, silanes and other coupling agents, polymer surface modification, relevance to adhesion acid base acid-base, dynamic surface characterization, mittal tissue, films, coatings, coupling agents, powders fibers, wood products, papers, polymers, monolayers, bioadhesion, ophthalmology, surface science, instruments,  liquid, solid surface energy, surface tension interface, interfacial tension analysis,  quantitative measure of the wetting of a solid by a liquid. Analysis characterizes the wettability of a surface by measuring the contact angle. Contact angle describes the shape of a liquid droplet resting on a solid surface. The roughness of a surface improves the wettability for hydrophilic surfaces; hydrophobic surfaces. Young's equation, which interrelates the contact angle and surface tensions of the liquid and solid phases. International Symposium on Contact Angle, Wettability and Adhesion. The angle of contact is the angle between the tangent to the periphery of the point of contact with the solid. Capillarity is an effect when liquid in a narrow vertical tube becomes elevated or depressed. When a liquid does not spread on a substrate (usually a solid), a contact. angle (θ) is formed which is defined as the angle. Contact angle measuring unit for characterization of hydrophobicity of film surfaces are used in controlling cleaning processes. A computer controlled contact angle analyzer makes it easy to measure static and dynamic contact angle, along with surface tension and surface energy. CONTACT ANGLE MEASUREMENT is a common method to obtain surface energies of materials. The measurement by itself is nothing novel.
