Overview
Fungilab CV003-111 Capillary Viscometer is a precision measuring instrument based on the Ubbelohde Viscometer principle, using the Ubbelohde DIN size Ia specification, suitable for liquid viscosity measurement in the range of 10 to 50cSt.
Features
1. Ubbelohde DIN standard design
2. Accurate measurement of 10~ 50cSt viscosity range
3. Suitable for a variety of liquid samples
4. Easy to operate, reliable measurement results
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
• Make sure the liquid completely wetting the capillary wall
Measuring temperature is constant
• Check the cleanliness of the Viscometer before use
• Strictly follow the operation steps for measurement
• Use the appropriate standard liquid to calibrate
