Overview
The Fungilab CV004-101 Capillary Viscometer is a precision instrument for measuring the kinematic viscosity of liquids, using the Cannon-Fenske Opaque model, size 25, viscosity measurement range 0.5~ 2cSt.
Features
1. Using Cannon-Fenske Opaque opaque design, suitable for opaque liquid viscosity measurement
2. Provide accurate viscosity measurement range 0.5~ 2cSt
3. Measurement accuracy based on capillary tubing principle
4. Suitable for a variety of industries and scientific research fields
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. During the measurement, the time to flow out of the Capillary Viscometer is measured with a standard liquid with known kinematic viscosity, and then the time to flow out of the sample from the same Viscometer is measured. The viscosity of the sample is calculated.
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
Maintain a constant measurement temperature
• Viscometers need to be cleaned before use
• Strictly follow the operation steps to perform the measurement
• Select the appropriate size Viscometer to match the specimen viscosity range
