I work in oil and gas production and we use hydrometers frequently in our work. Our hydrometers have internal thermometers so that you can just take a gravity and temp at the same time. Womdering why the hydrometers you get from most brew places don't have them? Do yours?
Because you haven't started manufacturing them yet!

On Deck: Apfelwein
Fermenting: Oatmeal Stout
I've seen them- most online homebrew shops have them, I believe. I have a "stick on" thermometer on the outside of the fermenter to monitor fermentation temperature, so I don't need another way to measure temperature during the hydrometer reading.
