Toss out those old hydrometers.
You can probably get a nice setup of these for less than $10k.
Agitator beds for the batteries could be added if desired, but
I haven't looked for them. If I ordered any of this stuff I would
want a couple pocket protectors thrown in gratis.

LOL!

For checking SG under way a refractometer might be easier, on the
pocket at least! eg:
