Liquid surface tension meter

Technical features:

1. Adopting excellent domestic electromagnetic force balance force sensors with high precision and high repeatability characteristics.

2. Fast data collection rate, up to per second5Update the data to provide a more accurate description of the dynamic tension curve.

3. Embedded with various professional tension correction models, providing sufficient guarantee for high accuracy of measurement data.

4. 5The touch screen is spacious and easy to operate, with integrated display of current temperature, current tension, peak tension, equivalent tension and other information.

5. Simultaneously design two testing methods, platinum plate and platinum ring, and choose one or both at the same time.

6. Fully automated operation: automatically locks the liquid interface, automatically locks the peak tension, without any conversion, directly displays the tension value and tension curve on the screen. Automatically stop measurement, no manual operation required, reducing manual errors.

7. Full range automatic calibration, supporting weight calibration, pure water tension calibration, and ethanol tension calibration.

8. The automatic lifting platform controlled by a stepper motor has an accuracy of up to μ mmLevel, smooth up and down, no noise, rising through the touch screen.

9. The distinctive semi-circular arc door isolates the influence of external airflow.

10. Convenient platinum plate and platinum ring lifting bracket, easy to remove and install, and can be used to calibrate the accuracy of force values with standard weights at any time.

11. Using water and ethanol as standard substances, the sample can be automatically converted through a formula20°CThe tension value below.

12. Powerful data collection and management software, no need for manual recording; Users can query historical data at any time and export itEXCELData format, convenient for users to develop secondary data.

13. Meet the following standards but not limited to them:
