High-Purity Water Interfacial Tension Meter

The pure water interfacial Tensiometer evaluates the surface tension of liquids by measuring the intermolecular forces at the liquid surface. The instrument typically uses a platinum plate or platinum ring to contact the liquid surface, records the force required to detach from the liquid surface via a mechanical sensor, and converts it into a tension value. It is applied in scenarios such as detecting water purity, assessing the effectiveness of surfactants, and evaluating the adhesion of printing inks.
Selection
When selecting, focus on a measurement range covering the conventional 72 mN/m, with an accuracy of 0.1 mN/m. The platinum components must be corrosion-resistant and equipped with temperature compensation functionality. Consider the sample cell capacity and the stability of automatic lifting. Calibration should be accompanied by standard weights. The data processing function should support curve recording and output interfaces.
