The Falling Ball Viscometer KF10 is based on the measuring principle by Hoeppler. |
|
| |
|
It enables simple but precise measurements of the dynamic viscosity of light-transmissive |
|
| |
|
Newtonian liquids. It is preferably used in
research, in processing control and in quality
|
|
| |
|
control. |
|
|
|
| |
|
For the measurement of low viscosities and for the control of pseudoplastic behavior the |
|
| |
|
measuring range (DIN 53015) is extended by optional adjustment of the operation angle. |
|
| |
|
A special glass ball is added for measuring the viscosity of gases an vapours. |
