Kyowa Automatic Surface Tension Meter DY-300

The DY-300 is a fully-automatic, multi-purpose, and easy-to-use surface tensiometer for reliable measurements of surface and interfacial tension, lamella length, sedimentation behavior, and liquid density. With its repetitive measurement function, the DY-300 is the ideal instrument for measurements in quality control. The high-quality components and the durable design combined with a video user manual integrated into the software guarantee user-friendly operation. Optional, jacket or heater type stages and a thermometer are also available.

Features

  • “One-click” fully automated operation
  • Pre-wetting function to eliminate measurement errors caused by unsuccessful wetting of the Wilhelmy plate or du Noüy ring
  • Easy parameter setting to adapt to various measurement standards
  • Video user manual for user-friendly operation
  • Adjustable body leveling function
  • Calibration using external weights for periodic verification of measurement accuracy

Examples of use

  • Surface tension: Paints, inks, and additives used in coating processes
  • Interfacial tension: Transformer oils, emulsions, and surfactant solutions
  • Lamella length: Evaluation of paint leveling, coating foam stability, and fire-extinguishing agents
  • Sedimentation behavior: Flocculants for wastewater treatment and dispersion stability of paints and pigmented inks
