Does extremely hard water have any affect on  SG. readings?

If a hydrometer (calibrated for 60 degrees) is placed in 60 degree water (very hard) and reads 1.002 is the hydrometer faulty, or are the minerals changing the water's density?

Should serious calibrating of a hydrometer be done in distilled water?

Not earth shattering, but is a good trivia question.


Thanks,
Barry

Well, maybe. The obvious first question is, does the hydrometer still read 1.002 at 60F using distilled water? If so, then yea the hydro is out of calibration.  My guess is this is what you will find...if not well, we'll discuss it at that time?

Little off topic, but not by much.  I am a newbie to homebrewing myself.  I noticed that my hydrometer says that it's calibrated to 60 degrees.  Is there much change on the reading if the test liquid is at say 79?

If so is there a formula to take the diff in temp into account?

Thanks in advance,
Billy

Yes temperature does matter. I no longer have my calibration chart, but you can find it on the web.

Best way is to click hydro adjust (?) I'm not near Promash at the moment, input the sg reading, sample temperature and record the adjusted reading. Clicking OK will adjust the value in the screen you came from for you.

That is why I no longer have my chart.

Hope it helps,
Barry

Thanks Barry.  Not only am I new to homebrewing, but new to promash as well.  Not too long after I submitted this post, I saw where to adjust for temp.
