DY-500 / DY-700 Surface Tensiometers

The DY-500 and DY-700 share the same body design and only differ by the integrated weighing system, with the DY-700 offering 10 times the readability of the DY-500. Both are fully automatic, high-precision, and easy-to-use surface tensiometers for reliable measurements of dynamic contact angle and powder contact angle, in addition to measurements of surface and interfacial tension, lamella length, liquid and solid density, sedimentation behavior, and evaporation rate.
Due to their accuracy and high versatility, both models are ideal for use in R&D as well as for reliable measurements for routine quality assurance.
High-quality components and the durable design combined with a video user manual integrated into the software guarantee user-friendly operation of the instrument and software.
