| Re: Need a calibration solution for your refractometer? Thanks Doc. I will check against this formula while the depression moves in and I get bored from being cooped up this weekend.
My refractometer instructions are to calibrate with pure water to '0' which I used my RO/DI and it seems to be on there even after a year so I am anxious to check it agaist the salt formula. Thanks for the link. |
