Essential for our printing line
These genuine German pens are incredibly reliable. We use them daily to check substrate readiness before printing, and the color change is distinct and immediate. Worth every penny for quality control.

Works well for coating checks
We use these to verify surface treatment on our coated materials. They are accurate and easy to use. Just remember to cap them tightly after every use to prevent drying.

Standard for our lab
Our laboratory requires certified testing tools, and these meet all our ISO requirements. The distinction between the 34, 36, and 48 dyne levels is very clear on various plastic films.

Reliable German engineering
You can tell the difference in quality compared to generic brands. The ink doesn't smear unnecessarily, and the test results are repeatable. Highly recommended for industrial use.

Good product, fast shipping
The pens work exactly as described. The only reason for 4 stars instead of 5 is that the caps can be a bit tight to remove initially, but once broken in, they are fine.

Accurate and consistent
I've tried cheaper alternatives, but they dry out too fast or give inconsistent results. The arcotest pens maintain their calibration well and the ink flow is perfect for precise testing.
Q: How long does the ink last once the pen is opened?
A: Once opened, the pens typically remain effective for about 3 to 6 months if capped immediately after each use and stored at room temperature away from direct sunlight.
Q: Can these pens be used on metal surfaces?
A: Yes, these dyne pens are suitable for testing surface tension on metals, plastics, glass, and ceramics, provided the surface is clean and free of oils.
Q: What indicates a failed test result?
A: If the applied ink beads up or retracts within two seconds, the surface energy is lower than the dyne level of the pen. A successful test shows the ink remaining as a continuous film for at least two seconds.
Q: Do these pens come with a calibration certificate?
A: Yes, genuine German arcotest pens are manufactured under strict quality controls compliant with DIN ISO 8296. A batch compliance statement is usually included in the packaging.
Q: Are replacement tips available for these pens?
A: No, the arcotest pens are designed as single-unit disposable items. Once the ink is depleted or the tip becomes damaged, the entire pen should be replaced to ensure accuracy.
