Operation video of surface tension meter

Aifei Si Precision Fully Automatic Surface Tension MeterIt is a professional measurement used to measure the surface tension value of liquids/The measuring instrument, surface tension meter, achieves accurate measurement of the surface tension value of liquids through principles such as platinum plate method, platinum ring method, maximum bubble method, hanging drop method, drop volume method, and drop weight method. This model of instrument utilizes the principles of mechanics to contact liquid through corrosion-resistant platinum rings and platinum plates, and converts the maximum force value into surface tension. While measuring the instantaneous surface tension of a liquid, software technology can be used to record the surface tension values that change over time.

Applied to the surface of liquids,The force that reduces the surface area of a liquid,It is called liquid surface tension. The reason for its formation is that there is a thin layer on the surface of the liquid in contact with the gas,It's called the surface layer,The molecules in the surface layer are sparser than those inside the liquid,The distance between molecules is slightly larger than that inside the liquid,The interaction between molecules manifests as gravity. Just like when you want to pull the spring apart, the spring actually shows a tendency to contract.

1Adopting Mettler high-precision balance module, coupled with high-precision data transmission and analysis system, the test data has high accuracy and repeatability.

2The stepper motor adopts a silent driving mode, coupled with a precision screw lifting shaft, resulting in minimal vibration during the testing process and no impact on sensor readings. Exquisite design ensures testing accuracy.

3We do not use two-point calibration method to calibrate instruments, but insist on using scientific gravity method to calibrate sensor readings, combined with platinum rings and platinum plates made by new processes, to ensure the accuracy of test results.

4The appearance design adopts a sturdy support structure, effectively avoiding cracking and damage during the transportation of the instrument.

5The high-speed microcontroller designed with imported chips has fast operation speed and high accuracy. The sensor acquisition strengthens the filtering function, further improving the reading accuracy of the sensor.

6The structural design of the cantilever beam and electromagnetic force sensor has been further improved, and the anti-interference ability of the sensor has been enhanced.
7Using displacement sensors with good linearity, sensitive output signals, accurate impedance matching, can ensure the accuracy of displacement.

8The instrument has a trigger stop function, and during the platinum plate testing process, it automatically starts and stops, calculates the immersion height, and accurately calculates the value through data conversion.

9The software comes with a calibration formula for testing and testing, which automatically adjusts parameters without the need for manual correction.

10Using a color LCD touch screen display, parameter settings, data reading, curve recording, etc. can all be completed on the touch screen. At the same time, it can be paired with a small thermal printer to directly print test results, making the operation very convenient.

11By testing and calculating models, it is possible to measure liquids with medium to high viscosity, achieving sample testing in special industries such as ink, paint, and petroleum.

12The lifting platform can be connected to an external super constant temperature bath for temperature control, and can also choose electric temperature heating and Peltier cooling for temperature control.

13Exquisite design, the instrument can directly read the internal temperature of the liquid.

14We have independent intellectual property rights, a comprehensive after-sales support system, and provide free on-site installation, debugging, and training services, as well as free software upgrades, effectively safeguarding users' rights to continuous high-quality software and hardware services.
