How to use a hydrometer in sea water?
   

Take the hydrometer by the tip, making sure your fingers are dry, and immerse it in the water until it floats on its own and freely. Be careful that no air bubbles distort the measurement. All you have to do is read the value on the scale, at the level of the water surface.
