The HAAKE Viscotester 550 is a rotational viscometer designed for fast and precise measurement of viscosity and flow behaviour for quality control and has established itself as a state of the art instrument in quality control.
Product Detail
The HAAKE Viscotester 550 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.
