Overview
Fungilab CV006-004 is a Capillary Viscometer, model U-Tube Reverse Flow BS/IP/RF size 4, with a viscosity measurement range of 20 to 100cSt. It is based on the principle of liquid flow in capillary tubing and is widely used in many industries.
Features
1. U-tube countercurrent design, conforming to BS/IP/RF standards
2. Provide accurate viscosity measurement, covering the range of 20~ 100cSt
3. Suitable for a variety of liquid samples, easy to operate
Principle
At a certain temperature, the kinematic viscosity of the 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 outflow time of the sample from the same Viscometer using a standard liquid with known kinematic viscosity.
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 for measurement of its outflow time from the Capillary Viscometer
2. Measurement of sample outflow time from the same Viscometer
3. 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 constant temperature during measurement
• Standard liquid calibrated before use
• Avoid capillary tubing or contamination
