Invented by Hubert J. Farnsworth
Purpose of invention Scanning brains
First appearance The Sting

The Gizmometer is an invention created by Professor Hubert J. Farnsworth and its main purpose is to scan people's brains. Farnsworth originally tries to use a guillotine to 'scan' Leela's brain, but Leela avoids it. When she asks for a way to scan her brain without removing her head, Farnsworth brings out the Gizmometer.

Note: This particular invention of Farnsworth's appears twice in the episode, but both times in Leela's dream. So it actually may not exist.
