Works well but pricey
The performance is undeniably good and accurate, but the price point is higher than some competitors. You get what you pay for in terms of consistency though.

Good quality, fast delivery
The build quality feels premium compared to other brands we have tried. The ink flows smoothly without dripping. Only wish the color coding was slightly more distinct in low light.

Highly recommended for manufacturing
Our production line efficiency improved since switching to these test pens. No more guesswork regarding surface readiness for coating or bonding.

Essential for our QC lab
These pens are incredibly consistent. We use them daily to test surface tension on packaging films before printing, and the results are reliable every time.

Perfect for adhesion testing
We needed a reliable way to check corona treatment levels on our plastic parts. This pen series makes the process quick and easy for our floor technicians.

You can tell this is a high-quality product. The tip durability is excellent, and it hasn't dried out even after a few weeks of intermittent use.
Q: How do I know which dyne level to select?
A: The required dyne level depends on your specific material and the subsequent process (printing, gluing, etc.). Please refer to your material supplier's specifications or conduct a gradient test.
Q: Is the ink safe to use on food packaging materials?
A: The ink is formulated for industrial testing purposes. While non-toxic, it should not come into direct contact with food products. It is suitable for testing the exterior of food packaging.
Q: Does this come with a calibration certificate?
A: Standard units do not include an individual calibration certificate, but batch test reports are available upon request for large orders.
Q: What is the shelf life of the ink once the bottle is opened?
A: Once opened, we recommend using the pen within 6 months if stored correctly with the cap tightly sealed to prevent evaporation.
Q: Can these pens be used on curved surfaces?
A: Yes, the flexible tip design allows for accurate application on both flat and moderately curved surfaces.
