I can't cancel it, the order already went through. I will test it. I have 14 days to try it out.

I wouldn't stress about it too much. The brix side is probably fine and the calculations are more accurate at lower numbers. The higher you go, the more the difference will vary.

Just make sure you calibrate it when you first get it.

So as long as I have the OG in brix, there's no need for a hydrometer? Granted, I'm gonna use one in the beginning to test it for accuracy.

Ok, I know I don't have a refractometer, but don't they ALL have automatic temp correction? isn't that kinda the reason for getting one?????

No not all refractometers have ATC. It depends on the mass of the prism. I know its low tech, but one with a much larger window will have ATC due to the mass cooling of the sample added.

Refracts use the refraction of the light through a known substance, and scale accordingly. That is if there is a linear equation to base it off of. If, as we use them, one would want a dual purpose unit, the scales cannot match up due to the addition of alcohol.

If you had one refractometer for brix and another for alcohol, you would be okay. Whereas a hydrometer just has a weight and floats due to the buoyency of the water.

Well you still need a hydrometer post fermentation unless you want to use additional approximation tables. I have a refractometer but my hydrometer still gets its fair share of use.

Well, pluging the data with the software, is there a need for a hydrometer?

Technically, no. I still use both at different times of the process so I can taste the sample.

I still use my hydrometer for OG and FG measurement. For me I still don't fully trust my refractometer. Mainly I use mine for pre-boil measurements. I am slowly trusting it more though, my last brew the hydrometer and refractometer were within .002 of each other.

i've only used mine a couple times, though each time so far i've used both a hydrometer and my refract just to see how they compare.. i've found that as long as i input the numbers correctly into beersmith they were both basically spot on.. i think my next batch i'll trust the refract and see how the brewday goes
