Fully automatic oil viscosity testerIt is an automated analytical instrument specifically used to determine the kinematic viscosity of liquid petroleum products (such as lubricants, fuel oils, etc.), widely used in the fields of petrochemicals, electricity, transportation, etc. Its measurement results are important indicators for evaluating the fluidity, lubrication performance, and applicable environment of oil products.

Working Principle:

Kinematic viscosity refers to the measurement of the internal friction force of a liquid flowing under the action of gravity. Its value is the ratio of the dynamic viscosity to the density of the liquid at the same temperature, measured in square millimeters per second (mm ²/s) or centimeters per second (cSt, 1cSt=1mm ²/s).

The core principle of the fully automatic oil viscosity tester is based on the capillary viscometer method: at a constant temperature, a certain volume of oil is passed through a standard capillary viscometer to measure the time it takes for the oil to flow through a specified scale in the capillary, and then the kinematic viscosity is calculated based on the viscometer constant. The formula is:

Kinematic viscosity (ν)=viscometer constant (C) x flow time (t)

　　Fully automatic oil viscosity testerThrough automatic temperature control, automatic timing, and automatic calculation, fully automated control of this process is achieved, reducing human operational errors. Automatically complete processes such as constant temperature, sample injection, testing, cleaning, and drying, supporting multiple viscosity meter specifications.

The fully automatic oil viscosity tester achieves efficient and accurate measurement of oil viscosity through automation technology, and is a key equipment for oil quality control and performance evaluation. Its stability and accuracy provide reliable data support for industrial production and scientific research experiments.
