Overview
Fungilab CV003-013 Capillary Viscometer is a viscosity measurement instrument based on the Ubbelohde ASTM size 4 standard with a viscosity measurement range of 2000 to 10000cSt. The product is widely used in a wide range of industries for the accurate determination of the kinematic viscosity of liquids.
Features
1. Ubbelohde ASTM size 4 standard design
2.The viscosity measurement range covers 2000~ 10000cSt
3. Suitable for a variety of liquid viscosity determination
4. Measurement principles based on mature capillary tubing
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. Calculate the viscosity of the sample according to the outflow time of the standard liquid and the sample
Notice
• Make sure the liquid completely wetting the capillary wall
Maintain a constant measurement temperature
• Use the appropriate standard liquid to calibrate
• Strictly follow the operation steps to perform the measurement
• Pay attention to the cleaning and maintenance of Viscometers
