This new line of viscometers includes three models (photo): the Viscotester E, for automatic flow-curve measurements with full PC control; the Viscotester D, for routine viscosity measurements with data transfer; and the Viscotester C, for easy, fast and accurate manual measurements. The rotational viscometers measure the resistance of a test substance against a pre-set speed, and the resulting torque or resistance determines the viscosity. A wide range of accessories allows for comparative measurements of highly viscous samples, such as creams, pastes and gels, or for viscosity measurement of small volumes. — Thermo Fisher Scientific, Karlsruhe, Germany
