Description
The TQC Sheen Viscosity Cup ISO 2431 is a high-quality immersion (dip) flow cup designed for measuring the viscosity of paints, coatings, lacquers and similar liquids in accordance with ISO 2431. The cup is equipped with a fixed stainless-steel nozzle and is available in either titanium-anodized aluminum or stainless-steel construction.
⸻
How it Works
- Immerse the cup completely into the liquid.
- Lift the cup vertically and start a timer as the liquid begins to flow out of the orifice.
- Stop the timer once the continuous flow breaks.
- Convert the measured flow time into kinematic viscosity (cSt) using a conversion chart or disc.
- Repeat the measurement under consistent temperature conditions for accurate and repeatable results.
This simple dip-and-drain method allows operators to perform viscosity checks quickly and efficiently, without the need for complex equipment.
