What do people use that they trust to check l salinity.
Used to use a refractometer albeit calibrated with rodi water on the zero line.
Bought a hanna salinity tester, calibratedcwith their fluid, granted I haven't been as calibrating as regular as I should but just tested the hanna and it was a smidge under 35ppt, calibrated it, tested the tank again and it was 33ppt, re calibrated it and the same result.
Used my old refractometer calibrated to zero with rodi 4x times and got 1.025.
So would you trust a refractometer calibrated to zero or this seemingly untrustworthy hanna item with proper calibration fluid, sensible answer suggests the hanna as im using the proper fluid but I've seen other people say these hanna things are not great.
Thoughts?
I used SEVERAL refractomters and hydrometers over the years. Then some people on a forum suggested this, and ive never used anything else since. it even comes with calibration liquid, and standard liquid to test it to make sure its 100% accurate. Its VERY reliable. only downside is the price. but its the best.
