Rotational viscometers (Brookfield methode)
Viscometers RC01 / RC02
for fast viscosity
measurements (Brookfield method)
The RheoTec
models RC01 and RC02 are rotational viscometers for easy and fast viscosity
determination as specified in ISO 2555 and other ASTM standards.
These standards define a viscometer to be used in torque, rotational speed and
spindle design. The viscometers RC01 / RC02 (versions L or R) comply with the
provided instrument specifications and are therefore 100% compatible to the Brookfield method.
These instruments with an easy-to-clean geometry give the opportunity to do
precise and time-saving single point measurements in daily routine as well as
to perform advanced viscosity determinations in research and development.
