Good product, strict storage needed
The pen works great when fresh, but the liquid evaporates faster than expected if not capped immediately after each use. Make sure to store it horizontally as instructed.

Accurate but pricey
These dyne pens are very accurate for checking corona treatment levels. They are a bit more expensive than generic brands, but you get what you pay for in terms of consistency.

Perfect for adhesion testing
Bought the full range from 18 to 105. Helps us determine exactly which primer or adhesive will work best on different plastic substrates. Highly recommended for industrial use.

Industry standard
This is the gold standard for surface tension testing in our facility. Easy to read results and the wide range of dyne levels available makes it versatile for all our projects.

Reliable and fast shipping
Received the original imported pens quickly. The cap seals tightly to prevent the liquid from drying out, which was a problem with our previous supplier.

Essential for our QC lab
We use these pens daily to test surface energy on packaging films before printing. The German quality is evident; the ink flows consistently and the results are reliable every time.
Q: Can this pen be used on metal surfaces?
A: These pens are specifically designed for non-porous plastics, films, and foils to measure corona treatment. While they can technically mark metal, they are not calibrated or intended for measuring surface energy on metallic substrates.
Q: Do you offer bulk discounts for purchasing the full set?
A: Yes, we offer tiered pricing for bulk orders. Please contact our sales team directly via the 'Contact Seller' button with your required quantity for a custom quote on the full 18-105# set.
Q: How do I interpret the results when using the dyne pen?
A: Draw a line with the pen on the surface. If the liquid beads up within 2 seconds, the surface tension is lower than the pen's value. If it remains as a continuous film for at least 2 seconds, the surface tension is equal to or higher than the pen's value.
Q: What is the shelf life of the liquid once the pen is opened?
A: While unopened pens have a shelf life of about 12 months, once opened, the liquid should be used within 6 months provided the cap is sealed tightly immediately after every use to prevent evaporation.
Q: Is this an original arcotest product or a replica?
A: We guarantee that all 'Original Imported Germany arcotest' pens sold through our store are 100% authentic, sourced directly from authorized distributors in Germany.
