LCR Meter

This is a pretty good LCR meter. Tests very low resistances, like your vape coils for example.

I also have this little LCR & Transistor tester. This thing is super cool and very cheap. It will test all kinds of things, diodes, mosfests, transistors, resistors, capcitors etc.

Here is the main page with all the documentation as well as a link to a good discussion about it on EEVBlog
