Re: baume meter
The reason for the test tube vs. the fatty graduate--you
have to fill a greater volume in the bigger diameter
I found $24.50 + shipping not too big a deal to get an
accurate idea of what different baume gums feel like.
Actually, the correct name is an hydrometer I
think...because googling "baume meter" has problems :)
BTW it isn't digital, it is kindof a weird looking
contraption, too. Not terribly high tech.
