glass floating hydrometers

[chakacris]

besides the size and type of scale are floatig glass hydrometers universal? should you get the same result from a beer & wine and a regular aquarium hydrometer?

I’m not sure about the settings for beer and wine ones. They work but I like a refractometer better.

You'd have to make sure that you get one with the right range of specific gravity, e.g. some of them only read up to 1.020. Also, almost all beer/wine hydrometers are calibrated at 60 degrees F, so you'd need to get calibration solution and figure out an offset for your tank temperature. At that point you might as well just spend a little extra money and get a refractometer.

I have one of these.
