DT-300 Electroacoustic Device for Zeta Potential Characterization

The DT-300 uses a pulse technique to measure the electroacoustic signals at frequencies from 1 to 10 MHz for colloids or liquids. It can also works as a standalone probe for on-line or in-sample measurements.

The theory for the zeta potential calculation has been developed and documented in multiple sources and has been experimentally verified up to 45 vol%.
