Viscometric systems for oils measurement
These are designed for the measurement of oil viscosity and the viscosity index according to the ISO and ASTM standards. In most cases Ubbelohde viscometers are used for this measurement. After the determination and display of the flow time by the measuring unit and its printout by the in-built printer, the dynamic and kinematic viscosity coefficient data are also calculated automatically, displayed and printed. The equipment can be linked to a PC to calculate, after the plotting of parameters needed for flow time measurements (viscometer number, number of repeated measurements, identification of sample data, etc.), numerical values characterizing oil properties according to the ISO and ASTM standards, i.e. viscosity index, accuracy and compliance. These values are stored with each measured sample. The protocol on measured samples can be printed out on a connected printer.
