Mineral Springs by Biogaurd?

You sure it doesn't need calibration? From what I've been reading, most of the units need to be calibrated first before they'll produce reliable results.

The Goldline units (including Mineral Springs) are not able to be calibrated....they do not actually test salinity, they test condutivity and covert it into a salinity reading. The reading will change with temerature even though the salt concentration is the same.
