ASTM D445 Manual and Cheap Kinematic Viscosity Tester
This tester is suitable to determine kinematic viscosity of petroleum products.
Principle:Under certain constant temperature,measure flow time of liquid with specified volume through one calibrated glass capillary(reverse flow type),multiplication of capillary constant and flow time is the kinematic viscosity of this liquid under that temperature.
I. Main technical features
1.The heating bath is made of glass,which is easy to observe
