Perfect for lab work

Our laboratory uses these daily for adhesion testing. The fast-drying formula saves us time, and the accuracy is spot-on compared to our liquid test kits.

Great for printing prep

Ensures our substrates are ready for printing without any guesswork. The 38 dyne marker is perfect for our specific film requirements. Will buy again.

Essential for quality control

This German-made dyne pen is incredibly reliable for our packaging line. The 38 dyne level test fluid dries quickly and gives a clear result every time. Highly recommended for industrial use.

Good precision, fast shipping

Works exactly as described for checking corona treatment on polyethylene films. The only reason for 4 stars is the price, but the quality justifies it.

Superior to generic brands

We switched from a cheaper brand to this BABTEST pen and the consistency is much better. No more ambiguous wetting results. The felt tip holds up well even after hundreds of tests.

Reliable tool

Solid construction and accurate readings. Make sure to cap it immediately after use to prevent evaporation, which is standard for all dyne pens.
