Petroleum Kinematic Viscometervalid until: 20 Oct 2022date published: 20 Oct 2021
Petroleum Kinematic Viscometer for conforms to GB/T 265-1988 Measuring and calculating method for kinematic viscosity of petroleum products, which is applicable to test the kinematic viscosity of liquid petroleum products (Newtonian liquids). It is used to measure the time when a certain volume of liquid flowing through a calibrated glass capillary viscosimeter under the gravity at a constant temperature. The product of capillary viscosimeter constant and flow time is the kinematic viscosity of liquid at that temperature.

The automatic kinematic viscosimeter for petroleum products can simultaneously activate four glass capillary viscometers for kinematic viscosity measurement under the same constant temperature, and each viscosimeter can be measured four times as a set of test data.
The instrument will automatically remove the timing result not meeting the tolerance according to the requirements of national standard method, and take the average of other timing values satisfying the tolerance, then calculate and obtain the kinematic viscosity value of the test.
When it is unnecessary to obtain the test result (Often to roughly observe the approximate kinematic viscosity value of an unknown sample), the kinematic viscosity value can be calculated at one time, twice or three times at any time.
