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 Wilhelmy plate or du Noüy ring
Easy parameter setting to adapt various measuring standards
Video user manual for user-friendly operation
Adjustable level of the body
Calibration by external weights for periodic inspection of measurement accuracy

Applications
Hardware

Surface tension: Paints, inks, additives for coating processes
Interfacial tension: Transformer oil, emulsions, surfactant solutions
Lamella length: Paint leveling, foaming stability of coatings and fire extinguishing agents
Sedimentation behavior: Flocculants used in wastewater treatment, stability of dispersions, such as paints and pigmented inks
