This is the best chain wear gauge I have seen. The measuring pins are placed between two chain links and as you move the gauge the pins spread out indicating chain wear from 0 to 1.

This tool gives an exact reading of chain wear and is very precise. It’s also more comfortable than the ones with a window. Portable and compact as well!
