Essential for our quality control

We use these pens daily in our packaging line to verify corona treatment levels. The German engineering really shows in the consistency of the fluid flow.

Reliable but pricey

Does exactly what it is supposed to do. The results are clear and easy to read. Slightly more expensive than other brands, but the accuracy is worth it.

Good product, slow shipping

The pen itself works well for tension testing. However, the delivery took longer than expected. Once it arrived, performance was as advertised.

Perfect for film testing

I work with polyethylene films and this pen gives instant feedback on surface energy. The brush tip is durable and hasn't frayed after months of use.

Great precision

Very satisfied with the purchase. It helps us avoid adhesion issues before printing. The labeling is clear and the pen feels sturdy in hand.

5 FAQ

Q: Is the refill fluid available for purchase separately?

A: Yes, refill solutions are available for most standard dyne levels. Please contact our support team with your specific pen model number for compatibility checks.

Q: How long does the test fluid last once the bottle is opened?

A: For best results, we recommend using the fluid within 6 months of opening. Always keep the cap tightly sealed when not in use to prevent evaporation.

Q: Does this come with a calibration certificate?

A: Standard units do not include an individual calibration certificate. If you require certified documentation for ISO compliance, please request it at the time of order.

Q: Can this be used on metal surfaces?

A: While primarily designed for plastics and films, it can be used on coated metals to test surface cleanliness and preparation, though results may vary based on coating type.

Q: What range of dyne levels does this specific pen test?

A: This specific listing is for a single value pen. Please select the specific dyne level (e.g., 38, 42, 46) required for your material from the variation options.
