Digital Surface Tension DST Series from S-EO (Surface Electro Optics)
The information of surface or the interfacial tension is critically important in applications such as detergency and emulsification and is also important for many biological processes. Especially, the Du Nouy Ring method and the Wilhelmy Plate method are commonly used for measuring surface / interfacial tensions.
The DST Series are precise tension meters (with Digital LCD display) for the measurement of surface (Liquid vapor) & interfacial tensions (Liquid – Liquid) using both the Du Nouy ring and the Wilhelmy plate.
The DST Series is upgraded version of the manual system and can measure the surface / interfacial tensions auto-matically and precisely using the Du Nöuy Ring method or Wilhelmy The sample stage can be automatically operated so that the errors from manual operation can be significantly minimized and the
accuracy can be maximized.
The surface and interfacial tension results can be gotten quickly with no additional calculations and the measured result and data can be shown easily on the LCD display and printed out.
The DST Series system is designed for Educational, Quality Control, and other multiple user applications. By simply operating the sample stage manually, you can get the surface / interfacial tension results quickly with no additional calculations. This system has two kinds of controllers for precisely operating the sample stage so that
the accuracy and reliability of results can be higher.
