Rheometer R/S Portable
Mobile and more
The Rheometer R/S Portable is a rotational viscometer (Searle principle) for mobile
use and laboratory operation.
The highly dynamic measuring drive systeme enables rotational tests where
either shear rate or shear stress can be pre-set (CSR and CSS).
Electronic unit, keypad, measuring drive system, and measuring spindle
coupling are integrated in a portable housing.
Special features
- build-in rechargeable battery and mains power
- parallel display of 4 optional parameters of viscosity, temperature, torque, shear rate, shear stress, rev (on a 4 line alphanumeric display)
- dust proof keyboard
- torque overload protection
- storage of the measuring conditions pre-set when Rheometer is switched off
- data buffering in the RAM for mains and battery operation
- serial interface for printer and personal computer
- user-friendly software RHEO3000 for Rheometer control and data evaluation
Optional Test Mode
- CSR - rotational test with shear rate control
- shear rate levels pre-set according to ISO 3219 defined speed and shear rates
- CSS - rotational test with shear stress pre-set (in connection with a computer system)

- viscosity
- shear rate
- shear stress
- speed
- torque
