Question on Refraactometer

[iloveswfish]

I bought this refractometer on Ebay and when i put the drops of water from my tank, and you look through it, what i see is something that says sodium chloride and not spicific gravity,,, is there something wrong with this meter.

I just looked through mine and it says SG/Salinty. Specific gravity is on the left 1.000 - 1.070, salinity on the right 0 - 100%ppt.

i just looked again and it says this sodium on the left and chloride on the right but the ad reads this: Portable Marine Salinity Salt Refractometer for Fish Tank Hydrometer Tester

Well, must be a very "off" brand because I don't see that labeling on any of them. Does it still work though - same scales?

Refractometers are used in all different kinds of applications... So sometimes the labeling is different... It could just be an off brand... You could test it by borrowing another refractometer and testing the same water with both

the brand is ATC is what it says on the front

I accidentally purchased a refractometer that reads brix I think. There is some sort of conversion that I don't understand and haven't used it since.
