The fictional products in the Futurama-verse are many. I doubt that page you linked would have captured them all... or even half of them. Just think about any time any character has used any tool of any sort. That itself is usually a product specific to Futurama (Baconated Grapefruit) or a Futurama-ified version of a real-life product (Tanning Butter).
And then there are your standard objects (pipes, wrenches, etc.) and your real-life products that do not seem to be modified for the show (Tri-Onimos, Play-Doh, Phillips head screwdrivers). I assume you are not considering these items, though.
Anyways, compiling a list of these items and products would be an interesting project during a run-through of the entire series.
Now, I would guess about 700 or 1,000
