Good product, short lifespan
The pen works perfectly while it lasts, but I found the fluid dried out in the tip faster than expected after opening, even with the cap secured tightly. Make sure to store it horizontally as instructed.

Fast drying formula works great
The quick-drying feature is a game changer on our fast-moving production line. We don't have to wait around to see results. The stroke remains visible long enough to judge but evaporates fast enough to keep the line moving.

Accurate tension testing
Been using Dyne pens for over a decade, and this brand is the gold standard. The 38 dyne marking was spot on when cross-referenced with our electronic tensiometer. Highly recommended for serious industrial applications.

Perfect for adhesion checks
We needed to verify surface treatment levels for a new adhesive application. This pen made the process simple and immediate. No complex setup required, just draw a line and observe. Will order more.

Essential for our quality control lab
We use these pens daily to test film surfaces before printing. The No. 38 level is perfect for our specific polyethylene rolls. The ink dries quickly and gives a very clear distinction between wetting and beading.

Reliable but pricey
Genuine UK Schumann quality is evident here. It performs consistently compared to cheaper alternatives we tried previously. Only giving 4 stars because the price point is a bit high for small batches, but you get what you pay for in accuracy.
Q: How should I store the pen when not in use to prevent drying out?
A: For best results, store the pen horizontally in a cool, dry place between 5°C and 25°C. Ensure the cap is clicked shut tightly immediately after each use to prevent solvent evaporation.
Q: Can I recalibrate this pen if I suspect it's inaccurate?
A: No, Dyne pens are single-use calibration tools with a fixed fluid formulation. If you suspect inaccuracy due to age or contamination, please replace the unit with a new one to ensure reliable testing data.
Q: What does it mean if the ink beads up instead of spreading?
A: If the ink beads up within 2 seconds, the surface energy of the material is lower than 38 mN/m. This indicates that the surface may require further corona treatment or cleaning before printing or bonding.
Q: Is this pen suitable for testing metal surfaces?
A: While primarily designed for plastics, films, and foils, it can be used on treated metal surfaces to check for cleanliness or coating adhesion potential. However, ensure the metal is free of oils that might interfere with the test.
Q: Does this product come with a certificate of analysis?
A: Yes, all genuine UK Schumann Dyne Pens are batch-tested. You can request a digital copy of the Certificate of Analysis for your specific batch number by contacting our support team with your order details.
