Good value for dual tips
Buying a dual-tip pen is more economical than buying two separate ones. The accuracy seems spot-on when compared against our liquid test kits. My only minor complaint is that the label could be slightly larger for easier reading.

Essential for our QC lab
We use these pens daily to test surface tension on packaging films before printing. The dual tips for 32 and 38 dyne levels are incredibly convenient and save us from carrying multiple single-value pens. The ink flow is consistent and the results are reliable.

Genuine German quality
As an authorized distributor product, you can trust the authenticity. The build quality is superior to generic alternatives we tried previously. The cap seals tightly, preventing the ink from drying out between uses.

Great tool, strict storage needed
The pen works perfectly for checking corona treatment levels on our extruded sheets. Just remember to store it in a cool place as specified; I left one in a hot warehouse and the ink degraded faster than expected. Otherwise, excellent product.

Reliable for industrial use
We have purchased several of these for our production floor. They are robust enough to handle daily industrial use. The clear distinction between wetting and beading makes it easy for operators to determine pass/fail status quickly.

Accurate and fast testing
This has streamlined our pre-treatment verification process. We get immediate visual feedback on whether the surface energy is sufficient for adhesion. The 32/38 combination covers most of our standard polyethylene needs.
Q: Is this product sold as a pair or a single unit?
A: This listing is for a single dual-tip pen unit that contains both the 32 mN/m and 38 mN/m testing fluids in one device.
Q: What should I do if the pen dries out?
A: Ensure the cap is clicked shut firmly after every use. If the pen dries out prematurely, it may be due to improper storage temperatures or a damaged seal; please contact support for replacement options if within warranty.
Q: Can this pen be used on metal surfaces?
A: Yes, the arcotest Dyne Pen is suitable for testing surface tension on various substrates including plastics, films, foils, and treated metal surfaces.
Q: How do I know if the ink has expired?
A: Expired ink may show inconsistent flow, changed viscosity, or fail to produce clear wetting lines. Always check the manufacturing date on the label and adhere to the 12-month shelf life recommendation.
Q: Does this come with a calibration certificate?
A: Yes, each pen comes with a Certificate of Analysis confirming the dyne level accuracy according to German manufacturing standards.
