Overview
The BZY200 ring method surface tensiometer is an upgrade of the BZY series, and the performance has been greatly improved. The instrument is widely used in the quality control process related to the interfacial tension, 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 realizes fast switching of accurate interfacial tension measurement through automatic motor control.

10. Chinese/English swap operation
Principle
High Accuracy measurement is achieved with a Sensor based on the principle of electromagnetic force equilibrating, and rapid switching of accurate interfacial tension measurement is achieved through automatic motor control. Users can calibrate with standard samples (distillation water and pure ethanol) to ensure measurement accuracy.
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

Steps
1. Use standard samples (distillation water and pure ethanol) to calibrate the instrument
2. Parameter setting via 4.3-inch Touchscreen
3. Place samples and make measurements
4. The instrument automatically displays the measurement results
5. Save measurement results and print main parameters, data and Linear dispersion
Notice
Standard samples should be calibrated before use to ensure measurement accuracy
Environmental requirements and reduced environment impact with Draft Shield
• Pay attention to data security management and use password management to prevent data deletion by mistake
• Measuring method according to measurement needs (platinum ring method or platinum plate method)
• Power supply voltage matching (110V or 220V)
