CNYST Surface Tension Analyzer Ring Du Nouy Tensiometer with Du Nouy Ring Method Accuracy 0.1mN/m Test Range 0-2000mN/m Lifting Speed 0－300mm/min Arbitrarily Adjustable 7-inch Touch Screen

About this item:

• Test Method: Du Nouy Ring Method
• High-quality core components ensure accuratemeasurement. Each machine is equipped with a high-precision mechanical electromagnetic force sensor, and the highest precision of surface tension can reach 0.001 mN/m.
• Illumination in the spacious measuring area, which illuminates the sample surface as well as the measuring body, makes positioning the sample extremely easy.
• According to the principle of buoyancy, thetensiometer immerses the object of standard volume in the test sample and calculates the liquid density value.
• Using a 7-inch touch screen, all information is clearly displayed on the screen and operations are completed. The machine can be used without a computer during operation, and supports Chinese and English interchangeable display.
  

Flexible and versatile surface/interfacial tension measurement methods:

• This serie tensiometer provides many expansion modules to expand the application scope of the instrument, which is used to measure various characteristics of surfaces and interfaces, which greatly improves the flexibility of its use. The main measurement principle is to accurately obtain the force between the measurement accessory or the sample to be measured when it is wetted by liquid. The instrument uses standard methods including the DuNoüy ring method and the Wilhelmy plate method(Please note that the package may not have both platinum plate and platinum ring. Please check the product description carefully.）. to measure the surface and interfacial tension of liquids. In addition, the instrument can be used to accurately measure the density of liquids with the necessary optional accessories.
• The spacious sample room is equipped with a transparent glass sliding door, which can protect the room from disturbed airflow. A built-in electronic level aids in precise adjustment of the sample stage for precise force measurement.
• The built-in measurement program can control the sample stage to ensure that there is no human interference in the measurement process. The running speed can be adjusted according to the experimental requirements and can be accurately repeated. The use of a dynamic, smooth-running drive eliminates negative vibrations. In addition, the long-term drift of the mechanical sensor is minimized.
• Through the 7-inch touch screen, simple and intuitive operation is realized. Intuitive operation on the touch screen is a feature of the new generation of tensiometers, allowing easy control of the sample stage and other components before and during a measurement.
• Built-in measurement data management menu, easy to view data and support external printer operation. All measurement data files can be transferred through a USB flash drive to convert to Excel files for easy management, recording and organization of measurement data.
• The machine program has a password management function to ensure that the data can be traced and prevent data modification and accidental deletion.

Application field:

• Evaluation of surfactant effectiveness and efficiency by measuring critical micelle concentration
• Wetting properties of tablets, active pharmaceutical ingredients and excipients
• Wetting of paints and coatings
• Oil aging degree detection
• Coating Wetting and Adhesion
• Cosmetics Development
• Study on Wetting Characteristics of Ink
