1 1 INTRODUCTION/INSTALLATION The miniAV®-X Automatic Viscometer The miniAV®-X Automatic Viscometer is designed to automate the timeconsuming sample testing and cleaning operations required for determination of kinematic viscosity in accordance with ASTM D445 specifications. The operator places the test sample(s) in small vials in the sample holder(s), enters sample identification information from the computer keyboard, and initiates testing with software keypad commands.
2 Measuring kinematic viscosity Kinematic viscosity is a measure of the internal resistance to flow of a fluid under gravity with the pressure head being proportional to the density of the fluid. For any particular viscometer, the time of flow of a fixed volume of fluid is directly proportional to its kinematic viscosity. Units of measure An accepted unit of kinematic viscosity is one centimeter squared per second, which is called one stoke.
