    In-line Surface Tension Meter

    Overview Products Knowledge Standards Terms
    The online surface tension meter measures the intermolecular forces of liquids by immersing a probe into the liquid, enabling real-time monitoring of changes in the liquid's surface tension. It is used in the production process control of coatings and inks, the adjustment of fountain solution concentration in printing, and the monitoring of the sizing process in papermaking to ensure process stability.
    Selection
    Select the probe material based on the corrosiveness of the liquid being measured, determine the temperature resistance level according to the process temperature range, and choose the probe size based on the installation space in the production line. Consider explosion-proof requirements and opt for intrinsically safe types, match the interfaces of the existing control system, and regularly calibrate and maintain with standard liquids.

    The Application of Contact Angle Measurement Instruments in the Study of the Relationship Between Ink Printing Wettability and Substrate Surface Tension
    This article introduces how a contact angle measuring instrument is used to study the relationship between wettability and substrate surface tension in ink printing. It first explains the principle, assessing the degree of wettability through the size of the contact angle, where an angle less than 90 degrees indicates good wettability.

    Determination of Static Surface Tension of Color Coatings Using the Platinum Plate Method with a Surface Tensiometer
    This article introduces the method of measuring the static surface tension of colored paints using the platinum plate method. It explains the principle, which involves calculating the surface tension by measuring the force when the platinum plate is lifted from the liquid surface.
    Surface Tensiometer: Interpreting the Invisible Forces on Liquid Surfaces
    Surface tension is the contractile force generated by the uneven forces acting on molecules at the liquid surface, influencing phenomena such as droplet formation and capillarity. Surface tension meters measure this force using techniques like the Wilhelmy plate method, the platinum ring method, or the pendant drop method. Their core components include force sensors, sample stages, and data processing systems.
    Surface Tensiometer vs. Contact Angle Goniometer: Which One to Choose for Wetting Studies?
    Surface tension meters primarily measure the surface tension of liquids and are suitable for analyzing the properties of liquids themselves, such as purity or the effects of additives. Contact angle meters, on the other hand, evaluate the wettability of solids by analyzing the contour of liquid droplets on solid surfaces, and are commonly used in surface treatment or coating research.
    Tips for Cleaning and Maintaining the Platinum Plate/Ring of a Surface Tensiometer
    In the field of laboratory testing, the measurement accuracy of a surface tensiometer largely depends on the cleanliness and intact condition of its key components—the platinum plate or platinum ring. This article explains how to maintain them.
    How does a surface tensiometer determine the success or failure of printing quality?
    Surface tension is a critical factor affecting printing quality, as it determines the wetting and adhesion of ink on materials such as paper and plastic. Accurate measurement and control of the surface tension of relevant liquids using a surface tensiometer are prerequisites for ensuring printing quality.
