Aqua Medic Marin Control

Today at my local fish store I noticed a new gadget. Perhaps in the USA it's more known, but the only thing we have to measure salinity here are a hydrometer and a refractometer.

 

Here is some additional info:

It seems like a very easy tool to use, it's a bit more pricey than a refractometer but I'm willing to spend the money.

 

Has anyone ever used this gadget??
