A Portable Kinematic Oil Analysis Solution for Field-Based Users
Kinematic viscosity is the most widely understood and monitored physical property for lubricants. Measuring kinematic viscosity at a fixed temperature in locations other than a controlled laboratory setting has been a process/quality-control requirement for some time. This paper describes how using solvent-free technology in the field can provide immediate and accurate kinematic viscosity measurements, even when compared to traditional laboratory viscometers. A case study is included comparing the measurement results between a portable kinematic viscometer and a capillary (modified Zeitfuchs) tube viscometer used in many commercial oil analysis labs.
