I. Overview

This instrument is a testing instrument designed and manufactured according to "GB/T265-88 Petroleum Products Kinematic Viscosity Determination Method and Dynamic Viscosity Calculation Method". The test principle of the instrument is to measure the time it takes for a certain volume of liquid to flow through a calibrated glass viscometer under the action of gravity at a constant temperature. The product of the flow time and the capillary constant of the glass viscometer is the liquid at this temperature. kinematic viscosity. Its unit is mm2/s. The product of the kinematic viscosity and density of the liquid at this temperature is the kinematic viscosity of the liquid. This method is suitable for the determination of kinematic viscosity of liquid petroleum products (Newtonian liquids)

II. Characteristics

1. Using a 5.6-inch high-definition color touch screen, the interface is clear and easy to use.

2. The instrument can measure 4 samples at the same time, and 4 experiments are carried out independently without interfering with each other.

3. Using PID temperature control technology, the temperature control precision is high.

4. Imported PT100 temperature sensor is used, with high temperature measurement accuracy.

5. The number of experiments can be selected according to needs, and the number of experiments on the same sample can be adjusted from 1 to 9 times.

6. The instrument can automatically control the temperature and automatically calculate the viscosity value, with a high degree of automation.

7. Parameters such as temperature control value, constant temperature time, fine-tuning temperature value, number of experiments, stirring speed, viscometer constant can be set, and the instrument can be saved after the setting is completed.
