Overview
Fungilab CV003-113 is a Ubbelohde DIN size IIIa Capillary Viscometer for the measurement of kinematic viscosity of liquids. The instrument is designed based on the principle of capillary method and has a viscosity measurement range of 1000 to 5000 cSt.
Features
1. Ubbelohde DIN standard design
2. Accurate measurement of 1000~ 5000cSt viscosity range
3. Suitable for testing a variety of liquid samples
4. Simple structure and easy operation
Principle
At a certain temperature, when the liquid flows in an upright capillary tubing in a state of complete wetting of the tube wall, its kinematic viscosity is proportional to the flow time. When measuring, use a liquid with known kinematic viscosity as a standard, measure the time it takes to flow out of the Capillary Viscometer, and then measure the time it takes for the sample to flow out of the same Viscometer, and calculate the viscosity of the sample.
Applications
Petroleum, chemical industry, light industry, electromechanical, national defense, transportation, coal, metallurgy, food, paper, Spinning & weaving, scientific research, institutions of higher learning
Steps
1. Prepare a standard liquid with known kinematic viscosity
2. Time measurement of standard liquid from Capillary Viscometer
3. Prepare the sample to be tested
4. Time measurement of specimen outflow from the same Capillary Viscometer
5. Measurement time based on the sample viscosity
Notice
• Ensure that the capillary tubing is completely wet
• Keep the test temperature constant
• Check the cleanliness of the instrument before use
• Strictly follow the operation steps to perform the measurement
