FANGRUI Q1000 Surface Tensiometer platinum plate method, range 1000mN/m accuracy 0.01mN/m

Features

1. The Q series tensiometer provides many expansion modules to expand the application range of the instrument, which is used to measure various characteristics of the surface and interface, which greatly improves the flexibility of its use. The main measurement principle is to accurately obtain the force between the measuring accessory or the sample to be measured when it is wetted by a liquid, the instrument uses standard methods including the DuNoüy ring method, the Wilhelmy plate method To measure the surface and interfacial tension of liquids. In addition, with the necessary optional accessories, the instrument can also be used to accurately measure the density of liquids.

2. The spacious sample room is equipped with a transparent glass sliding door, which can protect the room from disturbing air flow. A built-in electronic level helps to fine-tune the sample stage for precise force measurements.

3. 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 dynamic, smooth-running drives eliminates negatively affecting vibrations. In addition, the long-term drift of the force sensor is reduced to a minimum.

4. Through the 7-inch touch screen, simple and intuitive operation can be realized. Intuitive operation on the touch screen is a hallmark of the new generation of tensiometers, allowing easy control of the sample stage and other components both before and during a measurement.

5. The built-in measurement data management menu is convenient for viewing data and supports external printer operation. All measurement data files can be transferred through the U disk to be converted into Excel files, which is convenient for management, recording and arrangement of measurement data.

6. The machine program has a password management function to ensure that the data can be traced and prevent data modification and accidental deletion.
