Refractometer

[craig110768]

I have just started Hypo, at the moment i'm at 0.014.
I want to get the Refractomter, before going any lower though. How much money is one one them - that will do the job???

I just got mine the other day from northcoastmarine.com With shipping it set me back $110. I had it shipped next day because I was doing the same thing. Starting hypo and wanted to make sure my salinity level was correct. After checking my refratometer against my hydrometer I found the floating hydrometer was off by .003

off up or down?

my swing arm hydrometers were off by 0.005, what I thought was 1.025 was really 1.030, I got my refractometer off ---- $80.00 including shipping, best money I have spent.
