The need for a viscometer to accurately predict the cranking characteristics of oils in engines at low temperatures led to the development of a reciprocating viscometer. This paper describes the ...

Viscosity changes with temperature, and it is recommended to use calibration oils certified at the specific temperature for optimal viscometer performance. Image Credit: Paul N. Gardner Company, Inc.

This article explores viscosity, covering definitions, measurement considerations, viscometer selection, and the symbiotic relationship between viscosity and rheology. The critical elements to ...
