Liquid surface tension coefficient tester

FMD2090 typeLiquid surface tension coefficient testerProduct Introduction

The surface tension of a liquid is an important parameter that characterizes its properties. There are various methods for measuring the surface tension coefficient of a liquid, and the pull-out method is a commonly used method for measuring the surface tension coefficient of a liquid. The characteristic of this method is to directly measure the surface tension of the liquid using a weighing instrument, which is intuitive and conceptually clear. The pull-out method is used to measure the surface tension of liquids, which requires high instruments for measuring force. Due to the fact that using the pull-out method to measure the surface tension of liquids is about 1 × 10^-3N～1×10^-2Therefore, an instrument with a small range, high sensitivity, and good stability is needed for measuring force between N. FMD2090 Liquid Surface Tension Coefficient Testeris a kind ofExperimental instrument for measuring the surface tension coefficient of liquids using the pull-out method.
