Where to buy a hydrometer

Yesterday I was at the home brew and meant to pick up a hydrometer for todays brew but i forgot. the homebrew store is bout 45 mins away. Is there any other stores i could look in to find one? Walmart, Plumbing supply? What other types of industry use this instrument?

I doubt you’d be able to locate one outside a homebrew supply store or online. I guess as a last ditch effort to know your numbers, pull enough off and refrigerate until you can order one or pick it up.

Any wineries nearby? Up here in Ohio, a lot of them sell equipment for the home winemaker.

Some pet stores sell aquarium hydrometers for saltwater tanks. I think they only go up to 1.060 though.
