Good quality, fast shipping
The pen works as expected for surface energy testing. The only reason for 4 stars is that the cap can be a bit tight to remove quickly during high-volume testing.

Accurate and durable
I appreciate the durability of the casing. We drop these often in the factory environment, and they keep working. The measurement accuracy is spot on.

Essential for our printing line
We use these pens daily to check corona treatment on our plastic films. The white ink contrasts well on dark substrates, and the tension reading is consistent with our lab results.

Reliable German engineering
Been using SHEELON products for years. This White Series pen is accurate and the felt tip holds ink well without drying out too fast between uses.

Works but pricey
The pen functions correctly and gives clear results, but it is slightly more expensive than other brands we have tried. You pay for the brand name.
