sita Dyno Tester+

  • Hand-held Tensiometer for Process
    Monitoring and Quality Control
    The new and robust hand-held Tensiometer measures the surface tension as well as the surfactant concentration easily and quickly in the laboratory and at the production line. The mobile DynoTester+ directly shows the measuring results on a comfortable display and alerts the user if defined limit values are exceeded.

    Display of surfactant concentration within defined limits
    Comparability of measuring values with all SITA lab and process measuring devices
    Adjustable high dynamic bubble lifetime range: 15 ms…20.000 ms
    Patented and optimized capillary for process use
    Robust device housing for atline measurement
    Comfortable suitcase for transport and device storage, also useful as working surface
    Intuitive operation: simple and fast measuring as well as controlling
    Mobile hand-held tensiometer: no PC or notebook required
    25 measuring profiles for bath control, process documentation and more
    Optional Windows-Software SITA-ProcessLog

    Application fields
    The DynoTester+ is especially used in following applications:

    - Controlling the surfactant concentration in industrial parts cleaning industry
    - Monitoring the surfactant concentration in electroplating baths
    - Measuring the surface tension of liquids at the plant (atline) or in the laboratory (offline)
    - Quality control of inkjet inks, paints and lacquers/varnishes
    - Incoming and outgoing inspections of surfactant containing goods
    - Mobile use for external work
    For your security our application engineers advise you, if the DynoTester+ is suitable for your application. Furthermore, we test your samples and develop an appropriate controlling procedure according to your processes.
    Result: The DynoTester+ optimally supports you in quality control and process monitoring.

    Measuring principle
    Like all SITA Tensiometer, the DynoTester+ is based on the bubble pressure method for measuring the dynamic surface tension of liquids.
    The principle of the bubble pressure method is, that an air stream is lead through a capillary into the process liquid. A sensor measures the pressure which is needed to generate a bubble.
