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 systeme enables rotational tests with controlled shear |
|
| |
|
rate or controlled shear stress (CSR and CSS). |
