Hyrdometer to use???

[SuperFudge]

Hiya Patrick,

A few samples in 4 swing arm type hydrometers that i and a friend had showed ranges .0022 upto .0026, :eek: I believe the most accurate and reliable among these was M3`s arometer,although effectivly it is still a swing arm type.(and still not very cheap at about $60)
It just uses a looser fit swing arm,with a ball bearing for a counterweight,I guess avoiding the arm joint that gets pitted with junk and fouling your reading on the other versions.

I would think that it is not too much of a concern to have any specific reading within reason,just that you have a reference point established.For that matter you could just purchase another $20 version,and always have something to compare to.
