I haven't tried my Tilt yet with fruit, but I suspect it will run into issues. As I understand it, it measures the S.G. by the angle it's tilted in the must ("so THAT'S how it got its name"). However, for an all juice batch, it would definitely work.
These are the numbers from when I first mixed up the Skeeter Pee batch I have going, then around the time that I pitched the yeast. Since I currently have it logging every 15 minutes for this batch, I was able to see that it fluctuated a bit as the must warmed up on the heating pad - it dropped down to 1.088 then climbed up to 1.094.
