Overview
The Fungilab CV004-209 Capillary Viscometer is a Cannon-Fenske Routine size 400 viscosity measurement instrument with a viscosity measurement range of 240 to 1200cSt. The product is based on the principle of capillary method and calculates kinematic viscosity by measuring the flow time of liquids in capillary tubing.
Features
1. Adopt Cannon-Fenske Routine standard design
2. Wide viscosity measurement range covering 240~ 1200cSt
3. Suitable for a variety of liquid viscosity determination
4. Compliance with international standards
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. Use a standard liquid of known kinematic viscosity to calibrate and measure its time from capillary tubing
2. Load the sample to be tested into the same Capillary Viscometer
3. measurement of time from capillary tubing
4. Calculate the kinematic 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
• Standard liquid should be calibrated before use
• Strictly follow the operation steps for measurement
• Pay attention to the difference in measurement range of different models of Viscometer
