Refractometer

[EmilyB]

I purchased my refractometer from northcoastmarines (shipped via mail). I see they have the new ones with the stronger pins..... I only use it to make sure the SeaTest is working mostly, or when I want a really precise measurement.

It is important to note that not all hydrometers are temp corrected. (The SeaTest is)
