Rotational rheometer Physica MCR 302 by ANTON PAAR

The Physica MCR 302 rotational rheometer from Anton Paar is a device used to test the rheological properties of various materials. It allows you to perform analyzes (rheological tests) under conditions of constant shear rate (CSS) or constant shear stress (CSR). It allows for full characterization of the viscoelastic properties of fluids (e.g. flow curves, viscosity curves) over a wide temperature range. The Physica MCR 302 rotational rheometer is equipped with a powerful electronically commutated synchronous motor, a digital instrument using the latest digital signal processing (DSP) technologies, a high-precision air bearing with a built-in normal force sensor and a temperature control system in the range of -20 to 200 oC . Innovative systems such as: Toolmaster™ and TruGap™ allow automatic recognition of gauges and accessories and automatic gap measurement.
