Good value for money
Accurate readings compared to our lab equipment. Only giving 4 stars because the cap can be a bit tight sometimes, but overall a solid product.

Essential for quality control
We use these pens daily in our packaging line to ensure proper adhesion on poly films. The results are consistent and the felt tip lasts a long time.

Reliable and fast
Makes testing surface energy incredibly quick. No need for messy liquids anymore. Highly recommend for any printing or coating operation.

Perfect for our needs
Ordered the full range from 30 to 60. All pens arrived well-sealed and working perfectly. Great for checking corona treatment levels.

Decent but dries out if left open
The pen works well when fresh, but you must cap it immediately after use or it dries out quickly. Instruction could be clearer on this.
Q: Can these pens be refilled once the ink runs out?
A: No, USA ACCU Dyne Pens are designed as single-use disposable units to ensure accuracy and prevent contamination of the test fluid.
Q: How do I know which dyne level pen to start with?
A: Start with a pen level slightly lower than your expected surface tension. If the liquid beads up, try a lower number; if it wets evenly for 2 seconds, try a higher number until you find the threshold.
Q: Are these pens suitable for testing metal surfaces?
A: While primarily designed for films and plastics, they can be used on treated metal surfaces. However, ensure the surface is clean and free of oils for accurate results.
Q: Do you offer bulk discounts for ordering multiple levels?
A: Yes, we offer tiered pricing for bulk orders. Please contact our sales team directly or add large quantities to your cart to see automatic discounts applied.
Q: What is the shelf life of these pens?
A: When stored upright at room temperature and kept capped, the pens typically have a shelf life of 12 months from the date of manufacture.
