RCYN-V Petroleum Product Kinematic Viscosity Automatic Tester, in line with GB/T265-1988 "Petroleum Product Kinematic Viscosity Determination Method and Dynamic Viscosity Calculation Method", is suitable for determining the kinematic viscosity of liquid petroleum products (Newtonian liquid). This method refers to the At a certain constant 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 that temperature (the temperature The product of the lower kinematic viscosity and the density of the liquid at the same temperature is the dynamic viscosity of the liquid at that temperature).
The automatic measuring instrument for kinematic viscosity of petroleum products adopts advanced fuzzy PID temperature control technology with precise temperature control and an accuracy of ±0.02°C. 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 It is 0.1°C and can be used as an ordinary constant temperature water bath.
The automatic kinematic viscosity tester for petroleum products can simultaneously use 4 glass capillary viscometers to measure the kinematic viscosity at the same constant temperature. 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 (often in order to roughly observe the approximate kinematic viscosity value of the unknown sample), the number of times can be set to a small value, such as 1, 2, or 3 times, which can be used in a shorter time The approximate kinematic viscosity value of the tested sample is obtained within, and then the number of timings is modified to 4 times, and the final kinematic viscosity value of the tested sample can be accurately obtained in strict accordance with the requirements of the national standard method.
Petroleum products kinematic viscosity automatic tester, using high-definition color touch screen technology, rich and clear interface content, fast and flexible touch screen response; using large-capacity memory chip, can save up to 2000 measurement results; using panel-mounted thermal After the measurement is completed, the printer will automatically and quickly print the measurement results and sample number, measurement time, viscometer constant, pipe diameter, kinematic viscosity value and other information.
