In order to serve for studies of viscoelastic and steady-flow properties of various non-Newtonian liquids, a self-recording rheometer has been manufactured, which can be employed not only as a cone-and-plate but also as a Couette type rheometer by exchanging minor parts. It is possible to drive or stop the rheometer suddenly by the use of electro-magnetic clutch. This enables us to measure transient phenomena such as stress-overshoot and thixotropy of polymeric and disperse systems. The thermostat has been equipped to keep temperature constant from room temperature to 300℃. The frequency and number of revolution range respectively from 10^<-4> to 1 Hz and from 0.05 to 500 rpm. Steady-flow properties of several disperse systems and polymer solutions as well as dynamic properties of polystyrene melt have been measured by means of this rheometer.
