YNND-H Kinematic Viscosity Tester, in accordance with GB/T265-1988 "Petroleum Products Kinematic Viscosity Determination Method and Dynamic Viscosity Calculation Method", is suitable for measuring the kinematic viscosity of liquid petroleum products (Newtonian liquid). This method refers to a constant At temperature, measure the time for a certain volume of liquid to flow through a calibrated glass capillary viscometer under gravity. The product of the capillary constant of the viscometer and the flow time is the kinematic viscosity of the liquid measured at this temperature (the kinematic viscosity at this temperature) The product of the density of the liquid at the same temperature is the dynamic viscosity of the liquid at that temperature).

YNND-H Kinematic Viscosity Tester, adopts fuzzy PID temperature control technology, accurate temperature control, and the accuracy can reach ±0.02℃. It can set 20℃, 40℃, 60℃, 80℃, 100℃ and other national standard temperature control points, and can set any temperature control (set temperature should be higher than room temperature), set temperature resolution The temperature is 0.1°C, and it can be used as an ordinary constant temperature water bath.

YNND-H Kinematic Viscosity Tester can use 4 glass capillary viscometers to measure kinematic viscosity at the same constant temperature at the same time. Each viscometer can be repeated 4 times as a set of test data. The instrument will automatically remove the timing results that do not meet the tolerance according to the requirements of the national standard method, and take the average of several other timing values ​​that meet the tolerance, calculate and obtain the kinematic viscosity value of the group of tests. When it is not necessary to obtain the measurement result accurately (usually in order to roughly observe the approximate kinematic viscosity value of the unknown sample), the number of timings can be set to a small value, such as 1, 2, or 3 times, which can be used in a shorter time Get the approximate kinematic viscosity value of the tested sample within, and then modify the timing to 4 times. The kinematic viscosity value of the tested sample can be obtained strictly according to the requirements of the national standard method.

YNND-H kinematic viscosity tester adopts high-definition color touch screen technology, with rich and clear interface content, quick and flexible touch screen response; using large-capacity memory chip, can save 2000 measurement results; using panel-mounted thermal printer , When the measurement is over, the measurement result and sample number, measurement time, viscometer constant, pipe diameter, kinematic viscosity value and other information will be printed automatically and quickly.
