Essential for our printing line
We use these pens daily to check surface tension on plastic films before printing. The Pink Series covers our entire range perfectly. Authentic German quality is evident in the consistent flow of the liquid.

Industry standard for a reason
If you need accurate surface energy testing, this is the tool to get. The Pink Series is easy to read, and the German engineering ensures longevity. A staple in our quality control kit.

Good product, fast shipping
Ordered these for our new lab setup. They arrived quickly and were well-packaged. The pens feel sturdy, and the cap seals tightly to prevent drying out. Would buy again.

Perfect for coating validation
I work in a coating facility, and we rely on the SHEELON pens to verify corona treatment levels. The 22-60 range is ideal for our varied substrates. Highly recommended for industrial use.

Consistent results every time
After trying several other brands that gave inconsistent readings, we switched to SHEELON. The difference was immediate. The ink beads up or spreads exactly as expected based on the tension level.

Reliable but pricey
These dyne pens are very accurate and help us avoid adhesion issues. They are a bit more expensive than generic brands, but the reliability makes them worth the investment for critical QC checks.
Q: Does this pen cover the full range from 22 to 60 in one unit?
A: No, the '22-60#' designation refers to the available range within the Pink Series. You typically purchase specific dyne levels (e.g., 38, 40, 42) individually or in sets depending on your testing requirements.
Q: Can I get a certificate of analysis with this product?
A: Yes, as an original authentic SHEELON product from Germany, batch-specific certificates of analysis are available upon request for quality assurance documentation.
Q: How should I store these pens to maximize their shelf life?
A: To ensure the 12-month shelf life, store the pens horizontally in a cool, dry place away from direct sunlight. Always recap immediately after use to prevent evaporation and contamination.
Q: Are these suitable for testing metal surfaces?
A: While primarily designed for plastics, films, and foils, they can be used on treated metal surfaces to check for cleanliness or coating adhesion potential, provided the surface is smooth and non-porous.
Q: What is the difference between the Pink Series and other color series?
A: The color series generally indicates different ranges of surface tension values. The Pink Series specifically covers the mid-to-high range often required for flexible packaging and printing applications.
