The DST Series are precise tension meters (with Digital LCD display) for the measurement of both surface (Liquid - vapor) & interfacial tensions (Liquid - Liquid) using Du Nouy ring.

The DST 30 is designed for Quality Control,Educational and other Multiple User Applications. The DST Series offers a cost effective and accurate solution to routine measurement of surface and interfacial tensions of liquid. By simply raising and lowering the sample with the manual or automatic stage, you can get the surface/interfacial tension results quickly with no additional calculations.

The DST 60 Automatic system is upgraded version of the manual system and can measure the surface/ interfacial tensions automatically and precisely using the Du Nouy Ring method. The sample stage can be automatically operated so that the errors from manual operation can be significantly minimized and the accuracy can be maximized. Get the surface and interfacial tension results quickly with no additional calculations, and the measured result and data can be shown easily on the LCD display and printed out.
