Overview
TQC Benchtop viscosity cup VF2048 is a viscosity test instrument made of titanium anodic oxidation aluminum material, in accordance with ISO2431 international standards, filter diameter of 3mm, suitable for rapid viscosity and conformity assessment in the viscosity range of 7~ 42cst. Designed for use with Newtonian or near newtonian fluids, this product provides High Accuracy and repeatability testing, smooth and easy to clean surface, ensuring long life.
Features
1. Titanium anodic oxidation aluminum material, durable and easy to clean
2. Filter diameter 3mm, designed for viscosity range of 7~ 42cst
3. Conform to ISO2431 international standards to ensure test accuracy
4. The filter part has a prominent design for easy operation
5. Using computerized machining technology, mass stability
6. Smooth and bright surface, prolonging service life
Principle
The TQC Benchtop viscosity cup works based on the principle of flow time of a fluid through a fixed diameter filter. When tested, the fluid flows out of the filter under gravity, and the time (in seconds) from the start to the first breakpoint of the fluid is measured, which represents the conditional viscosity of the fluid. By comparing the calibrated chart of the standard viscosity cup, the flow time can be corrected to obtain an accurate viscosity value.
Applications
Newtonian fluid test, newtonian fluid test, viscosity assessment, conformity assessment
Steps
1. Select the appropriate Benchtop viscosity cup (based on outflow time)
2. Ensure that the viscosity cup and test fluid are at the required experimental temperature
3. Confirm that the fluid is free of bubbles and debris
4. Sealing the outflow hole (can be used by hand), fill it with fluid, scrape off the excess test solution to the edge groove, and place the receiving cup
5. Release the outflow hole and start the timing, and end the timing when the fluid appears at the first breakpoint, recording the time (seconds)
6. Fixed Flow rate test method: similar to step 5, but stop timing when 50 ml of fluid flows out
Notice
• When cleaning the viscosity cup, use a suitable fine brush and solvent to avoid using methods or tools that may cause scratches
• It is recommended to buy at least one standard viscosity cup with calibrated certificate, and draw a correction chart by comparing the measurement results to correct the outflow time
• Viscosity cup channel length is short, any change will significantly affect the outflow time, need careful maintenance
• Ensure that the test fluid is free of bubbles and debris to ensure measurement accuracy
