Fluke is a well known manufacturer of electrical and electronic test equipment.

Piro speaks:
If i do any more electrical work on the house, i want to pick up a Fluke multimeter, so as is so often the case, a little bit of my own personal whims and preferences sneak into the comic.
Besides, you KNOW Fluke would make a good one. They have a good rep amongst engineers and electricians (i used to be (still am, technically) an architect, and i used to work pretty closely with the electricians and mechanical and plumbing guys on coordination issues with hospital renovation projects.
