Haake VT550 Rotational Viscometer

The Haake VT550 is a rotational viscometer designed
for fast and precise measurement of viscosity and flow behavior
for quality control and has established itself as a state of the art
instrument in quality control.

Product Details

The Haake VT550 is a Searle viscometer. A rotational
speed is preset and the flow resistance of the sample is measured
in other words, the torque maintaining the set speed is proportional
to the viscosity. All final information on the viscosity, shear stress
and the shear rate is calculated from the torque required, the set
speed and the geometry factors of the applied sensor. The results
are displayed digitally and can be printed simultaneously.

For viscosity measurements a total of 60 different rotational speed
steps are available. 50 out of these 60 are factory set; the
remaining 10 are user programmable. The 60 steps cover a wide
range reaching from 0.5 rpm to 800 rpm. The resulting torque is
measured via a non-contact, low displacement sensor which enables
the extended measuring range with perfect signal linearity over the
whole range. The operating temperature can be measured by PT100
probes located either in the sensor used or directly in the test material.
