The Beer Bug
« on: October 22, 2012, 01:42:19 pm »
It looks like the Beer Bug is looking for supporters of their Digital Hydrometer. They have some updated videos on their www.beerbug.com and http://www.kickstarter.com/projects/parasitx/the-beerbugtm-digital-hydrometer site showing more detailed info about the device.

Looks like a refractometer is much simpler to me.

Isn't a refractometer only effective for getting OG?  The Beer Bug is designed to monitor constantly during fermentation.

You can use a refract to get FG you just need to apply some correction factors to the reading. This is because, If I recall, the refractive index of sugar and alcahol are similar so the refractometer can't distinguish when alcahol and sugare are both present.

Sean Terril has a good calculator for this on his site.

I use Sean's calculator and it works very well.

Glad it's working out for you guys. Here's the direct link to the calculator: http://seanterrill.com/2012/01/06/refractometer-calculator/ There's also a spreadsheet you can download to track multiple batches.

It has nothing to do with how similar they are, it is just that they are both non-zero.

I recommend Sean's calculator too.
