Overview
Fungilab CV004-212 is a Cannon-Fenske Routine Capillary Viscometer with size 600 and a viscosity measurement range of 4000 to 20000cSt. The instrument is designed based on the principle that the flow time of liquids in capillary tubing is proportional to the kinematic viscosity, and is suitable for accurate measurement of the kinematic viscosity of liquids.
Features
1.Adopt Cannon-Fenske Routine standard design to ensure measurement accuracy
2. Wide viscosity measurement range, covering 4000 to 20000cSt
3. Suitable for a variety of liquid samples, easy to operate
4. Widely used in industry and scientific research
Principle
At a certain temperature, the kinematic viscosity of a liquid is proportional to the flow time when it flows in an upright capillary tubing in a state of complete wetting of the tube wall. The viscosity of the sample is calculated by measuring the time it flows from the Capillary Viscometer using a standard liquid with known kinematic viscosity, and then measuring the time it flows from the same Viscometer.
Applications
Petroleum, chemical industry, light industry, electromechanical, national defense, transportation, coal, metallurgy, food, papermaking, 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 liquid
4. Time measurement of specimen outflow from the same Capillary Viscometer
5. Calculate the kinematic viscosity of the sample according to the flow time
Notice
• Make sure the liquid completely wetting the capillary wall
• Instrument calibrated before measurement
Maintain a constant test temperature
• Use the appropriate standard liquid to calibrate
• Avoid sample contamination affecting measurement results
