Does anyone know where I can find an accurate hydrometer? The one I got with my first kit was spot on. Of course I broke it (broken hydrometer thread updated). I got another one and checked and it was 6 points off with plain water (same check as my previous one). I got another one and it is 4 points off plain water. This must be some bad karma for not treating my first one as good as it should have been treated, but are they all hit and miss? It doesn't seem that complicated of equipment. I know it is simple math to compensate, but I hate math.
