Works well but shipping was slow

The product itself performs exactly as described for surface tension checks. However, the delivery took longer than expected which delayed our project start.

Essential for quality control

This dyne pen is incredibly accurate for checking our corona treatment levels on packaging films. The liquid flow is consistent and the results are immediate.

Good value with refill

Having the refill included is a great bonus. The pen itself feels sturdy and professional. Only minor issue is the cap can be a bit tight sometimes.

Standard for our production line

We use these daily on our extrusion line. They provide quick pass/fail results that help us adjust our corona treaters in real time.

Perfect for lab testing

Easy to use and store. The markings are clear and the solution does not evaporate quickly even with frequent use. Great product overall.

Reliable German engineering

We switched to this brand from a cheaper alternative and the difference in consistency is night and day. Highly recommend for industrial use.
