ABSTRACT
Experimental techniques such as those used to measure specific values of viscosity (e.g. softening point) are still in common use, but are not as powerful as those in which a range of viscosities can be measured. Hence, only the Margules (1 to 106 Pa·s), parallel plate (103 to 108), and beam bending viscometers (107 to 1014 Pa·s) will be discussed here. These devices are manufactured and marketed by Theta Industries.
