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.
