Simultaneous measurement of viscosity, rheology, and electrical properties - rheometer
Rheo-IS
If the structure changes, the flow of electricity will also change! Newly developed accessory.
Emulsions, suspensions, and other structurally viscous materials exhibit diverse flow curves and require complex interpretations. To complement this interpretation, we have developed a sensor that can simultaneously measure dielectric constant and impedance while controlling temperature in the flow field. - Simultaneous evaluation of steady flow viscosity (flow measurement), dynamic viscoelasticity, and electrochemical properties - Measurable over a wide AC frequency range (4 Hz to 8 MHz) - Easily attachable to a Peltier temperature control plate - Integrated control of rheo-impedance/rheo-dielectric measurements with TRIOS software
