Dielectric testing capabilities is offered on the advanced research rheometer, ARES. The dielectric option (ARES-DETA) can be added to existing instruments, and provides additional information on the structure of polar materials. When operated simultaneously with the rheological measurement, the dielectric test is an excellent monitor for probing the material’s structure changes during flow.
