Essential for our printing line
These pens are incredibly accurate and easy to use. We use them daily to check surface energy before printing, and they have never let us down. Highly recommended for quality control.

Solid performance
Great tool for checking cleanliness on metal parts before bonding. It saves us a lot of time compared to sending samples out for testing. Fast shipping too.

Good value for money
Works as expected. The range covers all our needs for plastic film testing. The only reason for 4 stars is that the tip wears out slightly faster than expected with heavy use.
Q: Does this product come with a calibration certificate?
A: Each batch is tested for accuracy against standard solutions, but individual calibration certificates are not included with single pen purchases. Bulk orders may request documentation.
Q: Are these pens safe to use on food packaging materials?
A: Yes, the test fluid evaporates quickly and leaves no harmful residue, making it safe for testing materials intended for food contact, provided standard safety guidelines are followed.
Q: Can this pen be used on curved surfaces?
A: Yes, the felt tip is flexible enough to apply the test fluid on slightly curved surfaces, though flat surfaces provide the most consistent and easy-to-read results.
Q: How do I interpret the results if the liquid beads up?
A: If the liquid beads up within 2 seconds, the surface energy is lower than the dyne level of the pen. If it spreads evenly, the surface energy is equal to or higher than the pen's rating.
Q: What is the shelf life of these test pens once opened?
A: Once opened, the pens should be used within 3 to 6 months for optimal accuracy, provided the cap is sealed tightly after each use. Unopened, they last up to 12 months.
