Product description

Surface tension measurement – quick and flexible

The SITA pro line t15 is an all-round talent among bubble pressure tensiometers. The measuring device has a comprehensive bubble lifetime range from 15 ms to 20 s for measuring the dynamic surface tension. It automatically adjusts the chosen bubble exactly without a drift or time-consuming readjusting by the operator.

The Auto-Mode analyzes the dynamic behavior of the surface tension of surfactant containing liquids. Wetting characteristics of surface active liquids can be analyzed and the optimal bubble lifetime for the concentration control can be easily determined by the operator.
The Single-Mode carries out a quick measurement of a single surface tension value at a pre-determined bubble lifetime for a reliable control of the surfactant concentration of process liquids
The Online-Mode is used for a continuous monitoring of process liquids and for determining the temperature dependency of the surface tension of liquids.
The measuring data can be saved in the Tensiometer SITA pro line t15, transferred to a computer or printed by an optional protocol printer.The software SITA-LabSolution realizes a visual presentation, evaluation and further processing of measuring data.

Advantages:
- 3 measuring modes (Single, Auto and Online) adapted to different measuring tasks
- Easy and direct start of measurement
- Automatic adjustment of bubble lifetime – no drift, no re-adjustment necessary

    Measuring principle

     

    Like all SITA Tensiometer, the SITA pro line t15 is based on the bubble pressure method for measuring the dynamic surface tension of liquids.

    Therefore, as it can be seen in the picture, an air stream is lead through a capillary into the process liquid and the pressure development for the bubble generation is measured.

    Application

     

    Determining the optimal bubble lifetime for a control of surfactant concentration

    The picture shows the procedure of how to determine the optimal bubble lifetime for monitoring the concentration of a wetting agent.

    After measuring the dynamic surface tension of samples with different surfactant concentration in the AUTO-mode, the optimal bubble lifetime is chosen to be the maximum difference between surface tension values of the concentration range to be monitored.

     

    Analysis of the temperature behavior of process chemicals

    in the ONLINE-mode for determining the temperature compensation for monitoring the surfactant concentration.

     

    Continuous process monitoring

    in the ONLINE-mode for the documentation of process development.

     

    Quick measurement of surface tension

    for quality control and concentration control.
