YNND-H kinematic viscosity tester

YNND-H kinematic viscosity testerAccording to GB/T265-1988 "Determination of kinematic viscosity of petroleum products and algorithm for dynamic viscometer", it is suitable for determining the kinematic viscosity of liquid petroleum products (Newtonian liquids). This method refers to measuring the time for a certain volume of liquid to flow through a calibrated glass capillary viscometer under gravity at a constant temperature. The product of the capillary constant of the viscometer and the flow time is the kinematic viscosity of the measured liquid at that temperature (the product of the kinematic viscosity at that temperature and the density of the liquid at the same temperature is the dynamic viscosity of the liquid at that temperature).

The kinematic viscosity tester adopts fuzzy PID temperature control technology, with precise temperature control and an accuracy of ± 0.02 ℃. Multiple temperature control points specified by national standards such as 20 ℃, 40 ℃, 60 ℃, 80 ℃, and 100 ℃ can be set, and any temperature control can be set (the set temperature should be higher than room temperature). The set temperature resolution is 0.1 ℃, and it can be used as a regular constant temperature water bath.

The kinematic viscosity tester can simultaneously use four glass capillary viscometers to measure the kinematic viscosity at the same constant temperature. Each viscometer can repeat the measurement four times as a set of test data. The instrument will automatically remove timing results that do not meet the tolerance requirements according to the national standard method, and take the average of several other timing values that meet the tolerance requirements to calculate and obtain the kinematic viscosity value of the test group. When it is not necessary to obtain precise measurement results (often to roughly observe the approximate kinematic viscosity value of unknown samples), the timing times can be set to smaller values, such as 1, 2, or 3 times, so as to obtain the approximate kinematic viscosity value of the tested sample in a shorter time. Afterwards, the timing times can be modified to 4 times to strictly follow the national standard method requirements to accurately obtain the kinematic viscosity value of the tested sample.

The sports viscosity tester adopts high-definition color touch screen technology, with rich and clear interface content, fast and flexible touch screen response; Using a large capacity storage chip, it can store 2000 measurement results; Using a panel mounted thermal printer, the measurement is completed and the measurement results, sample number, measurement time, viscometer constant, pipe diameter, kinematic viscosity value, and other information are automatically and quickly printed.
