Accurate hydrometer search

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.

You can get pre-calibrated NIST certified hydrometers and thermometers. They do, however, come at a price.

The one's I've got from Williams have been the best. For the best accuracy you want one with a narrow range like a bottling hydrometer.

I have this set.

Fifty bucks for the set or $20 each.

It's nice to have a precision hydrometer for bottling.

Have you ever considered a refractometer? After my fourth hydrometer broke I picked one up for 23 bucks. You need to run a small conversion when you want to check fermented wort, but they're solid, and they won't fall over and break when you need them most.

Thanks for the links. I have thought about the finishing ones but have not pulled the trigger. I do like the AHS ones. The middle one would fit my needs pretty well. I do have a refractometer and it is one of the most useful things I bought. I almost didn't get it, thinking I would never need it.

Thanks again for all the info.

I have owned 4-5 maybe including the Williams one mentioned above. All were off! I broke my last one and decided phuck it and now use a decent refractometer. Hydrometers, who needs 'em.
