Toomanymatts Posted April 3, 2022 Share Posted April 3, 2022 What's the best salinity tester for the money? This needle tester is driving me bananas. Quote Link to comment
NanoGrant Posted April 3, 2022 Share Posted April 3, 2022 I use the D-D refractometer and it’s been really reliable. Fauna Marin do a 35ppt reference solution to calibrate refractometers with and get them dialed in. Opposite end of the scale is a digital one such as the Hanna Instruments one but it depends how much you are willing to spend. 1 Quote Link to comment
Jaren45 Posted April 3, 2022 Share Posted April 3, 2022 I use the hanna at work and at home and I'm a big fan. Just calibrate it weekly or so if you're using it often, the packets cost me $.98 1 Quote Link to comment
