Reading a 3 scale hydrometer

My dad bought me a hydrometer and then left the country. Now I don't know how to read all measurements.

1st scale: 1-13% (I presume this is the potential alc scale) 2nd scale: 1-26 3rd scale: 1-28 (this one starts a little higher than the previous but ends on the same place)

Any clue what the 2nd and 3rd scale represent?

Thanks!!

My best guess is that the scale that goes to 26 is degrees Brix, and that one marked in % is potential alcohol. You can test the first guess by making a solution of 10% table sugar. Add 10g of sugar to 90g of water and mix well. The Brix scale should read 10.
