Rheomat R 180
Portable and stand-alone rotational viscometer based on well-established principles of operation. It is unique for its easy use and wide measurement range. The Rheomat 180 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 and the results may be stored and put out to PC or printer. The viscometer R 180 has been engineered for rapid and reliable viscosity determination in both the laboratory and production environment.
The rotational viscometers are supplied as a complete system with 3 coaxial DIN measurement systems each, a calibration certificate, stand and a stable transport case; broad range of accessories are available, calibration services.
The Rheomat R 180 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 180 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.
The viscosity of a sample is characterised by a flow curve. These are generated automatically by the R 180 in the measurement programs. Up to 50 flow curves can be stored and outputted to a printer or PC. Of course single point measurements and constant shear measurements are also available.
