contact angle meter with function of measuring cleaniless
How does a contact angle meter accurately measure the contact angle value? For how many years have you been ensuring the accuracy of the measured contact angle? Whether it's testing the effect of plasma cleaning or characterizing the wettability of materials, the core premise of contact angle measurement must be to ensure that the test water is clean and the surface of the test sample is free from organic contaminants, especially oil or surfactant contamination. The only method to verify the cleanliness of the test sample surface is through the weighing principle surface tension module. Therefore, a contact angle meter without a surface cleanliness measurement function can only be a demonstration device that measures angles using circular or elliptical methods, rather than a professional instrument for quality control or material characterization in research and development.#contact angle meter #contact angle #surface tension
