斯托默·克雷布斯粘度计

旋转桨式黏度计是克雷布斯式黏度计，是测定非牛顿材料黏度的Z有用工具。由于大多数油漆都是非牛顿液体，因此本黏度计广泛应用于油漆工业。非牛顿材料的黏度，会随剪切速率的变更而变更，但用旋转桨式黏度计作测定时，是依靠那在一定剪切速率下所作的测量来进行的。

Krebs Viscometer Ref 407/407A
The viscosity of non-Newtonian materials depends upon the
shear rate applied. The rotating paddle exerts a constant rate
of shear by means of falling weight, the size of this weight
being relative to the viscosity. The weight is gradually
increased until a paddle rotation of 200 RPM is achieved.
This speed is displayed on either an LCD display or indicated via a stroboscope.

All instruments comply to ASTM D562
