Fully automatic surface tension meter

1) Product Introduction

ST5100Fully automatic surface tension meterIt is a high-precision testing equipment developed by Xiaxi Technology based on the core measurement principle of capillary rise method, suitable for gas-The measurement and research of surface tension in liquid systems are widely used in scientific research and industrial quality control in various fields such as chemical engineering, materials, energy, and biomedicine. The equipment adopts a dual capillary measurement method, which can effectively avoid the influence of environmental interference, reading errors, and other factors in single capillary measurement, ensuring the reliability of surface tension measurement results,

ST5100Fully automatic surface tension meterSuitable for systems with lower viscosity(Such as refrigerants, short chain alkanes, and short chain alkanesN2TheCOMixed systems, etc)The surface tension measurement star covers a wide temperature and pressure range, with a standard temperature range of-30-100C, and can be further expanded according to customer needs, while also supporting5MPaThe measurement within the pressure range can meet the rapid testing requirements of conventional room temperature and pressure, as well as adapt to research applications under special working conditions such as low temperature, high temperature, and high pressure.

The equipment adopts a humanized modular design, and the core testing device can be flexibly removed to facilitate cleaning and sampling operations, significantly optimizing the sample replacement process. During the temperature control process, sample replacement can be quickly completed without waiting for the overall temperature to stabilize, greatly reducing the waiting time for temperature control in a single test and effectively improving testing efficiency;At the same time, the modular structure facilitates later maintenance and component upgrades, extending the service life of the instrument. The equipment is equipped with a fully automatic temperature control system and an image acquisition and analysis system, which can capture the liquid level height in real time, monitor the sample status in the sample chamber, and have a simple and intuitive operation process. It can realize the process measurement of surface tension in different systems.
