Rheometer R/S+
for quality control, research and development
The Rheometer R/S+ 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 systems 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 RHEO3000 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
