Surface Tension Meter

Product Description:

Qualtech Products Industry Surface Tension MeterDigital Tensiometer – is a precision instrument to evaluate the surface tension of liquids or surfaces as for example demonstrated by the Interfacial Tension of Oil Against Water by the Ring Method. This Automatic Surface Tensiometer – Digital Tensiometer – is designed and engineered to measure the surface tension of liquids such as adhesives, paints, coatings and lacquers as well as to measure the interfacial tension between liquids, e.g. oils and water. In addition this Digital Surface Tension Meter is often applied in the field of quality control of industrial productions, e.g. electroplating.

This precision Du Noüy Ring Method Surface Tensiometer is user-friendly and ergonomic offering a large LCD Display with backlight for easy reading and Soft Touch Buttons combined with the newest microchip technology for highest accuracy and repeatability.

This Surface Tension Meter is a fully Automatic Surface Tensiometer performing a complete Surface Tension Test with the touch of a button.
This precision Digital Tensiometer offers advanced features, e.g. automatic temperature compensation (optional feature, please specify when ordering), average value calculation, direct printing (mini printer available as accessory, please specify when ordering) and auto power off protection.

This professional Digital Surface Tension Tester is the ideal partner for your laboratory and research to:

  • measure the Interfacial Tension between Oils and Water according to the Ring Methods, e.g. the Interfacial Tension of Petroleum Products & Water,
  • evaluate the Interfacial Tension between Mineral Oils and water as the Liquid-liquid Interface,
  • determine the Surface Tension of specimen liquids as the Liquid-gas Interface.

This Digital Tensiometer is designed and engineered in accordance with International Test Standards, e.g. ASTM D971-12 (Standard Test Method for Interfacial Tension of Oil Against Water by the Ring Method), ISO 6295.
