Versatile and user-friendly viscosity measurement for lab or in-situ applications

Feb 26 2021 Read 1037 Times

The proRheo R 180, from proRheo, is a highly versatile, yet user friendly rheometer used to measure the viscosity of a wide range of substances in both the lab and field. It includes a rechargeable battery that enables it to be used for approximately one hour at full load without connection to the power supply.

The proRheo R 180 is a rotational viscometer. Its open, concentric measurement system allows measurements by immersion. The measuring head and measuring tube are rigidly coupled; the measuring unit is driven by a direct-current motor.

A built-in microprocessor calculates the values for the viscosity with the aid of the measured torque, the set shear rate and the measurement system used. The sample temperature is measured by a Pt 100 sensor immersed in the substance.

The display shows you the following data:  the sample temperature T in °C,  the torque M in mN.m,  the shear rate D in s-1 ,  the shear stress τ (tau) in Pa,  the calculated viscosity η (eta) in Pa. s,  the measurement system, e.g. 11,  the program step, e.g. 6 during an automatic step measurement.

The proRheo R 180 can store 50 measurements of step programs or single point measurements. An attached printer records the measurement data. With the aid of the rhesy 80 evaluation software, measurement data can be transferred to an attached computer and evaluated thus allowing the proRheo R 180 to be incorporated in computer-aided data acquisition systems. The rhesy 80 control and evaluation software allows you to perform computer-aided measurements.
