The viscosity index is a widely used and accepted measure of the variation in kinematic viscosity due to changes in the temperature of a petroleum product between 40 and 100°C.
A higher viscosity index indicates a smaller decrease in kinematic viscosity with increasing temperature of the lubricant.
The viscosity index is used in practice as a single number indicating temperature dependence of kinematic viscosity.
Viscosity Index is sometimes used to characterize base oils for purposes of establishing engine testing requirements for engine oil performance categories
KN-2270 Viscosity Index Bath
Overview
KN-2270 Viscosity Index Bath conforms to the ASTM D2270 Standard Practice for Calculating Viscosity Index from Kinematic Viscosity at 40 and 100°C, it covers the procedures for calculating the viscosity index of petroleum products, such as lubricating oils, and related materials from their kinematic viscosities at 40 and 100°C.
Features
The instrument adopts advanced single-chip intelligent temperature control, timely temperature display working status such as time and other parameters;
It has outer Plexiglas insulation cover with uniform temperature distribution in the bath, which has good temperature control effect;
Four samples can be simultaneously used for the test, which makes the experiment faster and more convenient;
