Overview
Fungilab CV004-104 is a Cannon-Fenske Opaque Capillary Viscometer, model size 100, with a viscosity measurement range of 3 to 15cSt. The instrument is designed based on the principle of capillary tubing viscosity measurement and is widely used in liquid viscosity determination in many industries.
Features
1. Cannon-Fenske Opaque design for specific viscosity range measurements
2. Accurate viscosity measurement range covering 3~ 15cSt
3. Suitable for viscosity determination of opaque liquids
4. Meet Standardized Capillary Viscometer Specifications
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, first use the liquid with known kinematic viscosity as the 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. Fill Standard Liquid into Capillary Viscometer
3. Measurement of standard liquid flow time from Viscometer
4. Washing and drying Viscometers
5. Load the sample to be tested into the same Viscometer
6. Measurement of sample outflow time from Viscometer
7. Measurement time based on the sample viscosity
Notice
• Ensure capillary tubing is completely clean and drying
Maintain a constant measurement temperature
• The liquid must completely wet the wall
• Use the appropriate Viscometer specification to match the specimen viscosity range
• Strictly follow the operation steps to perform the measurement
