Rheomat R140
proRheo R140 ...
... is a well-established viscometer for fast and reliable determination of viscosity. The premise for developing the R140 was to achieve an excellent value for money solution, without compromising perofrmance or flexibility.
The Rheomat 140 works with all kinds of measurement systems: concentric cylinder, cone-plate, measurement systems conform to DIN 53019 or ISO 2555 etc. All relevant rheological parameters are shown simultaneously.
Use
The viscometer R 140 has been engineered for rapid and reliable viscosity determination in both the laboratory and production environment, especially for control of incoming goods and quality control.
A selection of possible applications is colours and coatings, foods, pharmaceuticals, cosmetics, plastics, chemical basics and much more.
Measurement principle
The Rheomat R 140 is a classical rotation-type viscometer which uses a motor driven bob rotating in a fixed cup. The sample is sheared in the gap between bob and cup. The measured shear stress is used to calculate the viscosity. Because of the versality of the R 140 viscometer a viscosity measurement can be made by immersing the measurement bob in an open vessel or in a closed measurement tube where temperature can be accurately controlled.
Measurement procedure
Taking a measurement starts by entering the measuring system, the desired rotational speed and simply pressing a key. Within some seconds the viscosity is shown on the display.

Standards
The three measuring systems according DIN 53018 include each a measuring bob and a measuring tube with cap. The radial diameters between measuring bob and measuring tube are equal and according to the norm. Thus measurements with these measurement systems can be compared with any other values obtained with DIN systems. The DIN systems can be used as relativ systems if the measuring bob is used with a bigger measuring tube or without any tube at all.
ISO Spindles
Measurements according ISO 2555 are very common. ISO spindles are rotational bobs with either a plate or a bell shape with measurements being carried out in a commercial beaker or container.
Messung
The R140 is a portable viscometer and can be directly immersed into a sample requiring measurement. The advantage is obtaining an immediate and exact determination of viscosity without having the problems of sample handling and tranfer arising when taking the sample to laboratory.
