Excellent precision
Very satisfied with this purchase. The tip allows for a controlled application of the test fluid, making it easy to read the wetting behavior immediately. A must-have for QC teams.

Essential for our quality control lab
We use these pens daily to verify corona treatment levels on our packaging films. The SHEELON pen provides consistent and clear results every time. Highly reliable for industrial settings.

Accurate surface tension testing
As a print shop owner, ensuring proper adhesion is critical. This German-made pen gives us confidence in our pre-press checks. The red fluid contrasts well against most substrates.

Standard in our facility
We have switched entirely to SHEELON pens for our dyne testing needs. They are durable and the calibration seems very stable compared to other brands we have tried previously.

Good product, fast shipping
The pen works exactly as described. It arrived quickly and was well-packaged. I deducted one star only because the cap feels slightly loose, but the fluid application is precise.

Reliable tool for technicians
Works great for checking treated plastics. The instructions included were clear. Just make sure to store it upright to prevent any potential leakage during long-term storage.
Q: How should I store the pen to maximize its lifespan?
A: Store the pen vertically with the cap tightly secured in a cool, dry place away from direct sunlight. Ensure the temperature remains between 15°C and 25°C.
Q: Can this be used on metal surfaces?
A: Yes, Dyne pens can be used on metals to check for cleanliness or the presence of oils, though they are most commonly used for polymers and corona-treated films.
Q: Is the test fluid hazardous?
A: The fluid contains formamide and other solvents. Please refer to the Safety Data Sheet (SDS) provided with the product and use appropriate personal protective equipment like gloves.
Q: What specific dyne level does this pen test for?
A: This specific listing is for the pen body; please select the desired dyne level (e.g., 30, 38, 42 mN/m) from the variation options at checkout, as they are sold individually by level.
Q: Does this come with a calibration certificate?
A: Each batch is manufactured under strict German quality standards. While a specific individual certificate is not included in the box, the product complies with ISO standards for dyne testing solutions.
