OK I know I should already have one, but with all the other stuff(RO, PH meter, lots of testing stuff, etc.) I just haven't yet.

Although I clean it ever time and it reads 1.000 in tap water I am worried about my Hydrometer. A friend just bought another brand and it reads .02 lower than mine!!
What Brand of Refractometer do you all recommend?? Thanks all Warren

I like regular hydrometers better. They use rules of gravity. Kind of like mercury in a thermometer. There just arent many parts that can mess it up. Outside of a bubble

I bought one form this site. It's super duper and well built. I use it along with my digital salinity monitor. It gives me peace of mind that my digital monitor is calibrated correctly.
