Great deal on a refractometer on Amazon

Just bought one on ebay. Shipped from cali to mass in three days. Paid $24.49 with free shipping. The exact same one. I love it. How has yours changed your brewday?

I take about 3x more readings with about 1/10th the effort. :)

Mid boil? No big deal since I don't need to let it cool. First and second (and maybe third) runnings? Piece of cake, just put a drop on and close to top! After I take a proper hydrometer reading and pour the sample back, it's really nothing to take that one last drop from the hydrometer tube and put it on the refractometer for a double-check.

Once you realize how much of a difference temperature makes to a hydrometer, and you get serious about good readings, the refractometer is a massive bargain in terms of simplifying your brew day.

And let's say you forgot to take a hydrometer reading before adding the wort to the carboy... well ok then. Let's have a race. You get a hydrometer reading, I'll get a brix reading. Let's see who wins. The sanitized handle of a SS spoon will give me the single drop I need. And let's add up how much wort we both lost too because you know you aren't gonna risk putting that nasty sample back in with your beer.

Now, to be honest, nobody needs a refractometer. It doesn't make your beer any better. However, once you've used one, it's hard to deny the convenience.
 
Ya'll realize that it appears to be a Brix scale reading exclusively? I guess it's easy enough to convert to SG though.

Personally, I like to take 1st runnings, 2nd runnings, pre-boil gravity and post boil gravity with my refractometer.

If I'm close to the desired post boil gravity as well as the proper quantity of wort, I'll sometimes cut the boil short by 5 or 10 minutes as long as there are no late hop additions.

Also, I use an 80 quart brew pot to do my brews in... mainly 5 gallon batches. When I'm finished my boil and the pot is cooled down, I don't have enough depth to float my hydrometer. I'll sometimes draw a sample for my hydrometer, which or course I pour down the drain after the reading. In other words, since I trust my refractometer, I just use that number for my notes as the SG and skip the hydro reading... ymmv :)
 
I have the same one that I paid roughly the same price for, and it has ATC and SG scale on it.

Makes it pretty easy..

If Brix and OG scale is important to you, I offer one at a slightly increased price.

I got mine from Bobby_M. Both the brix and SG scales actually work. One common problem people have is the SG scale being incorrect.
 
If you calibrate your refractometer with distilled water. Your SG reading should be spot on. I have also read that you should let the sample set on the prism with the cover closed for 30 seconds or so.
 
Looks like its so cheap because it ships straight from Hong Kong. Its only about $8 cheaper than the one from amazon, and if it arrived broken I would much rather deal with Amazon than a Hong Kong ebay seller. I wonder what freight for that from the US to China costs? Probably as much as the item itself..
 
Just ordered mine as well, only $2.50 more for expedited shipping 1-3 days.. I need to check gravity of a beer that is almost done...
 
Don't toss your hydrometer... refractometer is only accurate on fresh wort. Once alcohol is present the refractometer is not longer accurate.
 
At that, I'd check it against your hydro for a couple of runs before you trust it completely.

It's good for all grain brewers who want to check gravity as you are going. Once you pitch and it starts to ferment, they aren't useful really.

Is this true? I don't mind taking some sample from pre-boil wort and runnings using a hydrometer, but it would be very convenient to get proper FG readings for fermentation/bottling purposes.

It is true. A Refractometer is really only great for taking small samples, quickly when you are running off your mash, pre boil OG, and post boil OG.........

Once you start getting alcohol in there, it tosses the reads off. Some people will use it, but you'll need a chart to reference it.. At that point, for me atleast, I'm content to use my hydro, as it's more accurate at that point.

You can use it to measure at the end, you just have to do the proper calibration(In Beersmith/etc) to calculate your correction factor. Do this over like 5 brews to get a good average correction factor and you should be able to calculate your final gravity just fine. Keeping the hydrometer around is always a good idea though, just to double check. I dont use the refractometer as much for speed, which its great for, i like to use it as a second source of data to get a more accurate idea of my gravity. I hate reading hydrometers, there seems to always be a few millimeters between ranges..is it 1.065? Or 1.068?
