Viscometers

Viscometers

The new ROTAVISC series determines the viscosity of liquids in all areas of application ranging from the laboratory to quality control. The four devices measure in different viscosity ranges. Regardless of a simple or demanding viscosity measurement - the ROTAVISC delivers rapid and accurate results. The scope of delivery includes a standard spindle set ,  a protective bracket, temperature sensor, quick connector, hook connector and ROTASTAND stand.

Easy to operate
The generous 4.3" TFT display allows for an intuitive menu guidance. A digital spirit level also supports the correct set-up of the start-up condition. The simple ramp function simplifies repetitive tasks.

Highest measurement accuracy
The level of measurement accuracy of the ROTAVISC rotational viscometer for both Newtonian and non-Newtonian fluids is +/- 1 % of the measuring range. The reproducibility is +/- 0.2 %.

Stepless speed
ROTAVISC is a viscometer, which offers stepless speed adjustment.
