Essential for our printing line
These pens are incredibly accurate for checking surface tension on our plastic films. The refillable feature saves us money in the long run.

Great value for refills
Buying the refillable pen was a smart move. The fluid lasts a long time and the pen itself is durable enough for shop floor conditions.

Reliable DIN standard testing
We use these daily in our QA lab. They consistently match our laboratory grade results. Highly recommended for industrial use.

Accurate and consistent
No issues with drying out quickly like cheaper brands. The 38 mN/m level we ordered works perfectly for our polyethylene sheets.

Good quality, fast shipping
The build quality feels solid and the felt tip applies the fluid evenly. I wish the cap clicked a bit tighter, but overall a great product.

Perfect for adhesion checks
Before painting or bonding, I always test with this pen. It gives a clear wetting line that makes decision making easy.
Q: Is the 40mN/m pen suitable for corona treated film?
A: Absolutely. The 40mN/m level is commonly used to verify the effectiveness of corona treatment on polymer films.
Q: Does this pen work on metal surfaces?
A: Yes, these pens are designed to test surface energy on various substrates including plastics, metals, and glass prior to coating or bonding.
Q: Can I buy refill fluid separately for this pen?
A: Yes, we sell compatible dyne test fluid bottles separately for the 18-105 refillable series.
Q: How do I know when to refill the pen?
A: When the felt tip no longer releases fluid smoothly or begins to dry out despite being capped, it is time to refill the reservoir.
Q: What is the shelf life of the fluid once the pen is opened?
A: If kept capped tightly when not in use, the fluid typically remains effective for 6 to 12 months depending on storage conditions.
