If you are interested in making a DIY probe pen, you might want to take a look at this article.
If you happen to have an internal resistance tester, you can come up with the idea of making a probe pen for it. Once you have all the materials ready, you can start building it.
You wrap the sharp probe tip with heat shrink tubing, and you make a strain relief ring at the tip using enameled wire.
You take two empty pens and insert them into the structure.
You drill a hole.
You also make a strain relief structure at the bottom.
You pour 704 adhesive into the hole to fix the parts in place.
You install a rubber anti-slip sleeve and attach the pen cap to protect the probe tip.
Now it is finished.
Completed.
