Rheometer voor Reologische analyse
Rheometer RC20
for quality control,
research and development
The Rheometer RC20 is a rotational viscometer (Searle
principle) for quality control as well as for product development and
engineering research in the laboratory.
The highly dynamic measuring drive system enables rotational tests with
controlled shear rate or controlled shear stress (CSR and CSS).
Special
features
- microprocessor-controlled
measuring device for mains power operation
- torque
overload protection
- PC
controlled measuring by using Rheometer Software RHEO2000 for graphical
data-presentation and regression
- user-friendly,
dust proof keyboard for manual use
- integrated
alphanumeric display (4 lines) for optional displaying of current
parameters of viscosity, shear rate, shear stress, rotational speed,
torque, temperature
- data
buffering in RAM, storage of measuring data with and measuring-count for
up to 10 measurements with up to 4,800 data-points
- assortment
of measuring systems and attachments
