Hand-held Tensiometer for Process Monitoring and Quality Control

 

MEASURING THE SURFACE TENSION -
CONTROLLING THE SURFACTANT CONCENTRATION

The mobile hand-held Tensiometer measures the surface tension as well as the surfactant concentration easily and quickly in the laboratory and at the production line. It directly shows the measuring results on a comfortable display and alerts the user if defined limit values are exceeded.

PRECISE
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

     

    ROBUST
    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

       

      FLEXIBLE
      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

          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.

          Here you can find further application examples [..]

          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. (more...).
