Solid performance
Does the job well. The liquid lasts a decent amount of time even with frequent use. Instructions included were clear enough for our new technicians to start using them right away.

Essential for our QC lab
We use these pens daily to test surface tension on packaging films before printing. The results are consistent and the ink flows smoothly without drying out too quickly. Highly recommended for quality control teams.

Reliable industrial tool
Been using USA ACCU products for years. This dyne pen is no exception. It provides clear wetting lines which makes determining the dyne level very straightforward for our operators.

Accurate and durable
Great product for ensuring our substrates are ready for bonding. The build quality feels robust, and the measurements align perfectly with our lab's electronic tensiometer checks.

Perfect for adhesion testing
We needed to verify surface treatment levels on corona-treated bags. This pen gave us immediate feedback. The range covered all our testing requirements from low to high energy surfaces.

Good value, accurate readings
The pen works exactly as described. It helped us identify contamination issues on our polymer sheets. Only giving 4 stars because the cap can be a bit tight to remove sometimes, but the accuracy makes up for it.
Q: Is this safe to use on food packaging materials?
A: Yes, the test is non-destructive and uses a small amount of fluid that evaporates quickly. However, the tested area should not be used for direct food contact immediately after testing until the surface is confirmed clean or re-processed, as per your safety protocols.
Q: How do I know which dyne level pen to select for my material?
A: You should start with a pen value slightly lower than your expected surface tension. If the liquid beads up, try a lower value; if it spreads evenly for at least 2 seconds, that is your approximate dyne level. You may need a few adjacent values to pinpoint the exact rating.
Q: Does the kit come with a calibration certificate?
A: Each batch is manufactured to strict standards, but individual pens do not come with a unique calibration certificate. For formal ISO compliance requiring certified calibration, we recommend periodic verification against standard reference materials in your lab.
Q: Can this pen be refilled once the liquid runs out?
A: No, these pens are designed as single-use disposable units to ensure the chemical integrity and accuracy of the test fluid. Once empty, please dispose of them according to your local hazardous waste regulations.
Q: What is the shelf life of the test fluid inside the pen?
A: The typical shelf life is 12 months from the date of manufacture if stored properly. Ensure the cap is tightly sealed after each use and store the pen upright at room temperature to prevent evaporation or contamination.
