Fields of application
The Rheomat R140 viscometer is designed for fast and reliable determination of viscosity in the laboratory and production, especially for production and incoming goods inspection as well as quality assurance. The areas of application are diverse, such as paints and varnishes, coatings, food, pharmaceuticals, cosmetics, plastics, chemical base materials and much more.
Measuring principle
The Rheomat R 140 determines viscosity according to the Searle principle: a measuring body rotates in a stationary measuring cup filled with the sample. The force that the sample exerts against the rotation is measured and converted into viscosity in the Rheomat 140’s microprocessor. Depending on the measuring system used, these measurements comply with the DIN 53 018 or ISO 2555 standards.
Measuring method
The sample can be measured directly in the container using the immersion method. Advantages: Exact determination of the instantaneous viscosity, no decanting of the sample, minimal sample loss. If the measuring tube is fitted with the appropriate sealing plug, small sample quantities can be tempered 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. 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.

Our all-round entry model for laboratory & production
Reduction to the essentials without sacrificing quality or flexibility. This was the premise for the development of the Rheomat R 140, and it has been met in full. Such high precision in viscosity measurement at this unusually low price results in an unprecedented price/performance ratio. The extensive system spectrum enables viscosity measurement of a wide variety of samples.
- Measuring systems according to DIN 53018 for the determination of absolute viscosity
- Measuring systems according to ISO 2555
- Relative measuring systems for control measurements
- Anchor stirrer measuring systems e.g. for samples with particles
- Cone-plate measuring systems
- Special measuring systems according to customer requirements
A rotational viscometer for measuring viscosity with all commercially available measuring systems. The Rheomat R 140 combines easy handling for daily routine with the quality required for accurate viscosity determination. The measuring principle has been adopted from the proven Rheomat R 180. The reduction to the essential, necessary functions facilitates daily handling without sacrificing precision.
The Rheomat R 140 viscometer is designed for fast and reliable determination of viscosity in the laboratory and production, especially for production and incoming goods inspection as well as quality assurance. The areas of application are diverse, such as paints and varnishes, coatings, food, pharmaceuticals, cosmetics, plastics, chemical base materials and much more.
