The Electromagnetically Spinning Viscometer (EMS viscometer) is a rotational viscometer.

This new type of viscometer

​

• is suitable to measure fluids with viscosities in the range of 0.1 to 1,000,000 mPa·s.

​

• can automatically evaluate the temperature dependency of the viscosity in the range of 0 … 200°C within a very short time.

​

• is capable of performing determinations of the rheological behaviour of liquids by determining the share rate dependency of the viscosity.

​

• provides a better absolute accuracy and repeatability of the results than classical Rotational Viscometers.

​

The EMS Viscometer measures the viscosity of liquids through observation of the rotation of a sphere which is driven by electromagnetic interaction.

​

The EMS technology distinguishes itself from other rotational viscometers by three main characteristics:

​

• All parts of the viscometer which come in direct contact with the sample are disposable and inexpensive.

​

• The measurements are performed in a sealed sample vessel.

​

• The system requires only very small sample quantities from 90 µL.
