Essential for our QC lab
We use these pens daily to verify corona treatment levels on our packaging films. The German engineering really shows in the consistency of the ink flow and the accuracy of the dyne levels. Highly recommended for industrial quality control.

Standard for our production line
We standardized on these pink dyne pens across all three of our manufacturing plants. They are durable, easy to read, and the staff finds them very intuitive to use for quick cleanliness checks.

Consistent results every time
I have tried other brands that seemed to dry out quickly or give inconsistent readings. This SHEELON pen has lasted months and provides the same accurate result on the first stroke as the last. Very satisfied.

Good product, slow shipping
The pen itself is fantastic and does the job perfectly for measuring surface energy. However, the shipping took longer than expected. Once it arrived, though, it has been a great addition to our toolkit.

Perfect for adhesion testing
Bought this to test adhesion readiness on polyethylene sheets before bonding. The color contrast is excellent, making it easy to see if the liquid beads up or spreads. A must-have tool for any coating application.

Reliable but pricey
This pen works exactly as described. It gives clear results on whether the surface tension is sufficient for printing. The only downside is the price compared to generic brands, but you get what you pay for in terms of reliability.
Q: How should I store the pen to maximize its shelf life?
A: Store the pen horizontally in a cool, dry place away from direct sunlight and keep the cap tightly sealed when not in use to prevent evaporation.
Q: What is the difference between the pink and blue versions of this pen?
A: The color of the body typically indicates the specific dyne range series. Please check the label on the cap for the exact numerical range included in that specific pen.
Q: Is this safe to use on food packaging materials?
A: Yes, the test is non-destructive and the small amount of fluid used evaporates quickly. However, ensure the area is dry before the packaging comes into contact with food.
Q: Can this pen be refilled once the ink runs out?
A: No, the SHEELON Dyne Pens are designed as single-use disposable units to ensure the chemical integrity and accuracy of the test fluid are maintained.
Q: How do I know which dyne level to start testing with?
A: It is best to start with a mid-range value based on your material specifications, then move up or down depending on whether the ink beads up or spreads evenly.
