Physics:Mini-rotary viscometer
From HandWiki
The mini-rotary viscometer is a device used to measure the pumpability of an engine oil at low temperatures.[1] Engine oils must meet viscometric standards including those determined by the MRV in order to be classifiable within SAE J300 viscosity grades.
