Measuring Principle
The measurement of viscosity with the Rheomat R 120 is based on the SEARLE principle. The measuring body rotates at a speed(s) in a substance. The moment required to make the measuring body rotate at this constant speed is a direct measure of the viscosity of the substance.
Measuring Method
The sample can be measured directly in the container using the immersion method.This allows the exact determination of the instantaneous viscosity without sample loss.If the measuring tube is fitted with the appropriate sealing plug, small sample quantities can be thermostatted and measured.
Calibration
Regular calibration according to the manufacturer’s specifications guarantees the reliability of the measured values.The measurement inaccuracy is less than 1% of the current measured value.We therefore recommend that calibration be performed once a year. An additional check with standard liquids can be performed and increases safety.

The R120 is a rotational viscometer. Its versatile range of measuring systems allows measurements according to DIN, ASTM, etc. using the immersion method or with a closed system. Measuring head and measuring system are always rigidly coupled.
A motor current measurement is used to determine the torque required to rotate the measuring body in the substance at a specified speed. The viscosity is calculated from this measured torque, the specified speed level and the measuring system used. The evaluation of the variables speed (n) and torque (M) is carried out according to DIN 53 019.
The viscometer is characterized by the simplest handling as well as a large measuring range and since only one measuring system is stored, errors in the selection of the measuring system are excluded and comparable measurements are simplified. Due to its handy fit and low weight, the R120 viscometer is an extremely versatile companion for quality assurance in the laboratory and production.
It can be used both classically in the stand and for immersion by hand.
