Sorry - didn't mean to sound snotty - long day. Hydrometers, in my experience, are not that reliable. I have tried 2 different ones that my reading were all over the map on. If they would have consistently been off by X amount it wouldn't have been so bad but I would get high one time and low another time when I compared to a refratometer (sp). If you have one that you get the same test result on every time and can measure it against a refracto thingy you should be OK as long as you make sure that you are always testing with the correct temperature. Maybe someone can lend you one until you figure out which one is the most accurate.

Thanks everyone for your post.

I could bring my refractometer to the upcoming meet so we could calibrate your two hydrometers.

That would be awsome if you could, that way we would at least have a good idea

Thx

It appears that refractometers also need to be calibrated to a known sg solution near sea level. The only two refractormeters I tested against all displayed differant results while all three were calibrated to RO and distilled water.
