Hi,
I'm new to the forum, but not new to saltwater/reef. Been away from saltwater for about 15 years.
I have 2 refractometers, a Hanna salinity meter and an old school float hydrometer. Both refractometers have been calibrated with 1.026 solution and distilled water. The meter has been calibrated with the proper cal solution.
Both refractometers are showing the salinity @ 1.027. The meter is showing 1.024 and 1.025 at times. The hydrometer shows just a hair over 1.025.
Which would you believe is correct?
I'm thinking that the 2 refractometers are correct.
