If you want a quick and easy way to take gravity readings during the brewing process, then a refractometer is the tool for the job. Taking hydrometer readings during the brew tends to be a time-consuming process, and by the time you get a reading it may be too late to react. This is because you need to take a large sample and cool it to get an accurate reading. A refractometer allows you take instant gravity readings, with just one drop, at any point during the boil, or even during the run off of the sparge during an all-grain brew. These 'during the process' readings allow you to add more water or boil longer so you can attain exactly the gravity you desire.

Traditional refractometers without ATC are calibrated to work at 68°F. The ATC function allows you to use the refractometer in an ambient temperature range of 50-86°F (10-30°C). Since your sample is just one drop, and will quickly adjust to the temperature of the refractometer, the temperature of the sample is irrelevant. This unit also comes with a manual calibration knob that is secured with a lock nut. To calibrate place one drop of distilled water on the testing platform and adjust to zero if necessary. The LED light is a handy feature that helps illuminate the sample and make the scale easier to read.

BEST ANSWER: The LED light. When you look through the other one you need good natural light or a bright indoor light in order to see the scale.

Very Bad LED Light Design
The very poor design of the LED light and the far too many open connections provide lots of places for liquids to enter, corroding the contacts and disabling the light. Mine gave me about 5 readings before the light started getting flaky, and finally quit. I had to rebuild it using stainless steel shafts to get it to work again. Again - very poor design. To avoid the problem for a bit longer, make sure to rinse off that area with distilled water and dry it before putting the instrument away.

Very easy to use and matched my hydrometer out of the box. If only morebeer would tell us the pre-boil gravity of their kits!

Best investment I have ever made
With the proper correction calculator this works great. Scale is a little hard to read with old eyes, but much easier that my hydrometer.

Start with this. Don't buy it later
If you care about beer, get this first, get it with your first order. it is so much easier than a regular hygrometer to use, and it can get used all the time. I use it to measure the gravity out of the sparge to make sure I get every last sugar molecule out of my grain, and I use it to make sure my OG target is on when we pitch, and I use it to figure out what is wrong with my fermentation when it gets stuck. It's such a marvelous and easy to use tool! I don't even use the built in light. I have a clear sky window to look at. I also check the FG of every beer I like to check and see how they finish. Tip: fill the entire sample space to get a good clear reading. When checking fully fermented beer with CO2 bubbles, slosh the beer well and let stand before reading to get the best accuracy.

Awesome tool, wish i would have picked this up about 10 batches ago. Compared sample with old school hydrameter and numbers where spot on
