Are you mimmicking me?!Hell, to be honest I have no idea how you calibrate a hydrometer. The others have pretty much covered hygrometers. :wink:
Thick paste and 75%. :thumbsup:
:thumbsup:A hydrometer measures specific gravity and is one of the tools that home brewers use. I just figured you were making some beer! :wink:
This is what I would do as well.Well, I will be the odd man out and say do not waste time on the salt test. I have done some serious experimentation with it and found it to swing from mildly to wildly innacurate. Unless you get your mix exactly right, you will never know for certain your degree of accuracy. Spend the money for a calibration Humidi-Pak from one of our vendors and you will be assured of an accurate reading. I never recommend the salt test.
