Low Temperature Kinematic Viscosity Tester ASTM D445 / ASTM D2532

Detailed Product Description

Mô tả

The oil product kinematic viscosity automatic measuring instrument is a special test instrument designed and manufactured according to the national standard "GB265-88 petroleum product kinematic viscosity measurement method", which is suitable for determining the kinematic viscosity of liquid petroleum products. The instrument has the timing of the sample movement time and automatically calculates the final result of the kinematic viscosity. The method is suitable for determining the kinematic viscosity of a liquid petroleum product (referred to as Newtonian liquid) in units of m2/s, which is usually used in practice as mm2/s. The kinetic viscosity is obtained by multiplying the measured kinematic viscosity by the density of the liquid. The method is to measure the time when a certain volume of liquid flows under gravity through a calibrated glass capillary viscometer at a constant temperature, and the product of the capillary constant of the viscometer and the flow time, that is, the liquid is measured at the temperature. Kinematic viscosity. The product of the kinematic viscosity at this temperature and the density of the liquid at the same temperature is the kinematic viscosity at that temperature.
