would this refractometer work for salt?

hello and my dad has a brix refractometer for measureing the sugar content in plants and i was wondering if it would work for salt water
thanks

I dont think the scale would be correct

Yea but if it is calibrated for sugar, I dont think it would work for salt. It works off of scattering light based off of the type of substance and concentration of it.

but don't they both measure the same unit specfic gravity?

Buy 1 that is made for saltwater aquarium just to be on the safe side. Not worth risking a tank from crashing.

Get a calibration solution for a tank, the solution should be 53 mS/cm (which equals 35ppt, or a sg of 1.0264), and set that at some arbitrary point on the scale, say 15. Then just aim to get your saltwater to that point.

No. Taken from Wiki.
Degrees Brix (symbol °Bx) is a unit representative of the sugar content of an aqueous solution. One degree Brix corresponds to 1 gram of sucrose in 100 grams of solution and thus represents the strength of the solution as a percentage by weight (% w/w) (strictly speaking, by mass).

Relative density, or specific gravity,[1][2] is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.
