Overview
The BZY200 surface tensiometer is an upgrade of the BZY series, with a significant improvement in performance. The instrument is widely used in interfacial tension related quality control processes, such as emulsifying agent, wetting agent and detergent detection. It has the characteristics of reliable performance, easy to use, and does not rely on computers. It can provide accurate and reliable analysis under the needs of large-scale sample testing. The instrument uses automatic motor control to achieve fast switching of accurate interfacial tension measurement.

Principle
High Accuracy measurement is achieved by using the Sensor of electromagnetic force equilibrating principle, and fast switching of accurate interfacial tension measurement is achieved through automatic motor control. Users can use the platinum plate method or platinum ring method for fully automatic measurement, and can directly display the tension surface value or interfacial tension value without calculation.
Applications
Ink, inks analysis printing/Spreader tendency, wettability, quality control, cleaning agent analysis surfactant absorption rate, properties, study the appropriate concentration, auxiliary liquid research aggregation and diffusion behavior, cosmetic analysis emulsion or suspension agent dispersion, Stability and wettability, Eletroplating analysis wettability, quality control, pesticides, traditional Chinese medicine analysis adsorption, dispersion, stability, paints, Coating analysis dispersion, stability, wetting, etc., transformer oil and other petroleum products The size of the oil-water interfacial tension value is closely related to the purity of the new oil and the deterioration of the running oil, water treatment sewage treatment, water quality analysis
