It looks like http://Engineering Plot free font by David Kovalchik

Looks like something close to this previous discussion about Leroy Lettering machine, very close to Engineering Plot (if not matching).
Some alternatives : Planscribe, Leroy Lettering Light Beta 01, Gravur Condensed, Rendering, Simpliciter Sans, Gordon, Register Sans, Primer Print, Report, Oxymoron, TGL 0-16

EDIT: Fivos is confirming Engineering Plot

Yes, I think that's it.

Thanks a lot!

And thanks for the alternatives, Ryuk. I think it is indeed Engineering Plot, but those look very interesting too.
