A high-temperature contact angle meter is a physical-property testing instrument used in fields such as chemistry, materials science, metallurgical engineering, and physics. Its primary applications include ultra-high-temperature liquid–solid contact-angle measurements, as well as non-contact measurements of ultra-high-temperature liquid surface tension and density.

Specifically, a high-temperature contact angle goniometer employs optical imaging and image contour analysis to measure the contact angle, wettability, interfacial tension, surface energy, and other surface properties of samples under high-temperature conditions. These performance parameters are crucial for understanding material surface characteristics and optimizing related processing procedures.

In addition, high-temperature contact angle measurement instruments are frequently used to characterize the surface properties of metallic materials. By measuring and analyzing contact angle data, researchers can gain a deeper understanding of the surface behavior of metals under high-temperature conditions, thereby providing critical guidance for material selection, processing, and application.

Therefore, high-temperature contact angle measurement instruments are widely applicable in research, production, and quality control, serving as indispensable tools in thermodynamics and surface science.
