Gravity
Total newb here, I have a couple questions if some of you folks don't mind answering them for me.
I've done alot of research in the last couple days and some info I can't find answers for.
Like gravity,what is the diffrence between a Narrow range hydrometer and a finishing hydrometer?
How does it measure sugar level?
I know what finishing gravity is(FG) so do I need two hydrometers?
Thanks.
Marv.
