Perfect for printing prep
Before running large print jobs, we test the substrate with this pen. It ensures proper ink adhesion. Very easy to use and the results are immediate. A must-have tool.

Accurate and durable
I have been using Dyne pens for over a decade, and this German model is among the best. The values are accurate compared to our lab equipment. Highly recommended for quality control teams.

Reliable standard tool
Does exactly what it says on the tin. The ink dries at the correct rate for accurate reading. Would be nice if it came in a multi-pack for better value, but the single unit quality is top-notch.

Essential for our packaging line
We use these pens daily to check the corona treatment on our polyethylene films. The German Schlon brand is consistent and reliable. The ink flows smoothly and gives clear results every time.

Good quality, fast shipping
Arrived quickly and well-packaged. The pen works as expected for surface tension testing. I deducted one star only because the cap feels slightly loose, but it doesn't affect performance.
Q: What is the shelf life of the ink once the pen is opened?
A: Once opened, the pen should be used within 3 to 6 months for optimal accuracy. Always ensure the cap is tightly sealed after each use to prevent evaporation.
Q: Is this pen refillable?
A: No, these Schlon Dyne pens are designed as single-use disposable units to maintain calibration and hygiene standards. They are not refillable.
Q: Can this pen be used on metal surfaces?
A: Yes, this Dyne pen is suitable for testing surface tension on various metals, provided they are clean and free of oils or heavy oxidation.
Q: Does this come with a calibration certificate?
A: Standard units do not include an individual calibration certificate, but they are manufactured under strict ISO controls. Bulk orders can request batch certification upon purchase.
Q: How do I interpret the results if the ink beads up?
A: If the ink beads up within 2 seconds, the surface tension of the material is lower than the value marked on the pen. You should try a pen with a lower mN/m rating.
