Overview
The FANGRUI Q2000 platinum ring method surface tensiometer uses standard methods such as the Dinui lifting ring method and the William plate method to accurately measure the surface and interfacial tension of liquids. Equipped with a spacious sample chamber, electronic level and 7-inch Touchscreen, the instrument supports automatic lifting and fully automatic measurement, and has built-in ST Flash software for data management. It is suitable for a variety of industrial and research fields.
Features
1. Provide expansion module, support Dinui lifting ring method, William plate method measurement of surface and interfacial tension, and optional Accessories measurement of liquid density.
2. The spacious sample room is equipped with a transparent Glass door, and the built-in electronic level is used to precisely adjust the sample stage.
3. Built-in measurement program to control the sample stage, adjustable running speed, dynamic smooth drive to eliminate vibration and reduce mechanical Sensor drift.
The 4.7-inch Touchscreen allows for intuitive operation and easy control of the sample stage and Miscellaneous components.
5. Built-in data management menu, supports U disk transfer and conversion to Excel file, which is convenient for data management, recording and sorting.
6. The program has a password management function to ensure data Traceability and prevent modification and erroneous deletion.
Principle
Based on the accurate measurement of the force between the parts or the sample to be tested when the liquid is wetting, the instrument uses standard methods such as the Dinui lifting ring method and the William plate method to detect the force value change through the mechanical Sensor to calculate the surface and interfacial tension of the liquid.
Applications
Surfactant evaluation, tablet wetting characteristics, paints and Coating wettability, oil aging degree detection, coating wettability and adhesion, cosmetic development, ink wetting characteristics research
Standards
ASTM D971、ASTM D1331、ASTM D1417、DIN EN 14210、DIN EN 14370、ISO 304、ISO 1409、ISO 6889
Steps
1. Use the electronic level to adjust the sample stage to level.
2. Measurement parameters, such as lifting speed, are set through Touchscreen.
3. Place the sample and start the automatic measurement program.
4. Data is automatically collected and saved, and can be transferred or printed via a USB flash drive.
5. Data analysis and management using ST Flash software.
Notice
• Ensure that the glass door of the sample chamber is closed to avoid airflow interference measurement.
• Calibrate instruments before measurement to ensure accuracy.
• Use password management to protect data security.
• Adjust the lifting speed according to the experimental requirements to avoid affecting the results too quickly or too slowly.
• Regularly check platinum ring specifications to ensure compliance with standards.
