Overview
Fungilab CV006-010 is a Capillary Viscometer model U-Tube Reverse Flow BS/IP/RF size 10 designed for the measurement of kinematic viscosity of liquids from 20,000 to 100,000 cSt.
Features
1. U-tube countercurrent design, conforming to BS/IP/RF standards
2. Covering the high viscosity range of 20000-100000 cSt
3. Suitable for a variety of liquid viscosity measurement
4. Measurement accuracy based on capillary tubing principle
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 its outflow time using a standard liquid with known kinematic viscosity, and then measuring the time the sample flows out of 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. 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
• Viscometer calibrated before use
• Avoid using liquids beyond the viscosity range
