Fields of application

The R180 rheometer, for example, is designed for fast and reliable determination of viscosity in the laboratory and factory, especially for production and incoming goods inspection as well as quality assurance.

Measuring principle

The R 180 is a classic rotational viscometer. The measuring body rotates in a fixed measuring tube and is driven by a motor. The substance to be measured in the measuring gap generates frictional resistance, which is recorded via motor current measurement. The result is the viscosity of the substance. The measurement is carried out in the immersion method or in a closed and thus temperature-controlled system.

Temperature detection

When determining viscosity, it is essential to record the temperature. This measurement is carried out by a built-in Pt100 temperature sensor, which is placed directly in the sample above the measuring gap.


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. In accordance with DIN 53019, calibration is performed gravimetrically at the manufacturer. This should be renewed once a year. An additional check with standard liquids can be carried out and increases safety.

Measuring Systems and Accessories

ISO Spindle Set

Relative measuring system for measuring substances with low viscosity. Consisting of 5 different sized spindles that can be used in any form of measuring cup and provide reliable results.

DIN Measuring Set

Special DIN standardized measuring systems in 3 different sizes, consisting of measuring body, measuring tube and sealing plug. Depending on the viscosity of the samples to be measured, 3 different sizes are supplied and allow comparable measurements under exactly constant conditions.

Anchor Measuring Set

Relative measuring system for measuring substances with higher viscosity. Supplied in 4 different sizes and can be supplemented with so-called centering aids.

The R180 is up for anything

Flow curves characterize the flow behavior of substances. The Rheomat R180 determines flow curves automatically or controlled via a PC. Up to fifty recorded rheograms are stored and then output via our Rhesy software. Of course, measurement at constant shear stress is also possible.

The fields of application are manifold, e.g.

Paints and lacquers
chemical base materials and much more.

The R180 is a portable, mains-independent rotational viscometer based on a proven principle. It is characterized by the simplest handling and a large measuring range. All rheologically relevant parameters are displayed simultaneously and constantly updated. The cast-iron housing and the extremely durable keypad, make the R180 almost indestructible.

Measurements and displays depending on temperature are no longer a problem, thanks to the built-in PT100 sensor, and the internal rechargeable battery allows complete flexibility in mobile use.

It is by far the most versatile viscometer in our range and is used daily by large companies such as BASF Coatings.
