Yup, this one does but costs a little more.
My Mac would explode if I tried to use Morebeer's excel sheet, so I found an online calculator for FG at this site.

IMHO - refractometers are fantastic for brewday, but absolutely useless once yeast is in the equation.
I've tested those calculators against what a hydrometer reads, and they are not at all accurate.
I love my refrac. and it is very helpful on brew day. Be sure you get one with Auto temp control. For final gravity, I bought a narrow-range (.95 - 1.020) hydrometer at my LHBS for 20 bucks. So refrac. on brew day, ultra accurate hydrometer for FG.
What is the basis of a brewhouse correction factor?
I'm planning on using both at first. How far off was the refractometer? Inherently it seems that the correction would be accurate. Which correction did you use?
