The viscometer measures by means of the mechanical resistance of any liquid that acts in the opposite direction to the rotational movement of a spindle. This results in a torque that is recognized by the viscometer and converted into a viscosity value. With an accuracy of ± 1.0%, the rotary viscometer is a very precise measuring device despite the high measuring range of 10… 2,000,000 cP or mPa*s. With the immersion resistance temperature sensor on the viscometer, the temperatures of the liquids to be tested can be measured between 0 and 100 °C or 0 and 212 °F.

This viscometer is used, for example, in the quality control of oils. Many oils change their viscosity depending on the temperature. Thanks to the timer function, the rotary viscometer can work independently for the period set by the operator. In the meantime, the measurement data is transferred from the rotary viscometer to a PC via the RS232 interface. Software for the rotary viscometer can then display the temperature profile and also the viscosity profile graphically and in tabular form. An optional printer can also be connected directly to the viscometer in order to print out the respective measured value.

The viscometer can be adapted to a wide variety of environments. The viscometer can be leveled using the height-adjustable feet so that the measuring spindle is always vertical in the medium to be measured. To help with this, there is a bubble level on the head of the rotary viscometer. The height of the test device can also be adjusted by approx. 25 cm from the viscometer in order to position the spindle appropriately.
