Flexible and versatile surface/interfacial tension measurement methods 

★Q series 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. 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.
