ASTM D1655 Fully Automatic Low-Temperature Kinematic Viscometer

KN-1655 Fully Automatic Low-Temperature Kinematic Viscometer

Overview

KN-1655 Fully Automatic Low-Temperature Kinematic Viscometer conforms the ASTM D445 Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (and Calculation of Dynamic Viscosity). It is used to test the of liquid petroleum products, both transparent and opaque, by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer. The dynamic viscosity, η, can be obtained by multiplying the kinematic viscosity, ν, by the density, ρ, of the liquid. Under certain constant temperature. The range of kinematic viscosities covered by this apparatus method is from 0.2 to 300 000 mm2/s at all temperatures
