The RSG-100ATC refractometer reads in both Brix and Gravity. This refractometer features a corrected scale. What is a corrected scale? Read on.
Gravity to Brix Accuracy
Typical dual scale refractometers use a linear 4 x gravity to Brix conversion. That’s fine and dandy up until around 1.049. At that point this linear scale starts to become inaccurate. Brix 11 does equal 1.044, but Brix 12 does not equal 1.048. It is 1.049. It’s only 1 point off here, but up at Brix 24, it’s up to 5 points off. Brix 24 equals 1.101 not 1.096.
All this to say that this model of refractometer uses a more accurate, non-linear gravity to Brix scale.
From the manufacturer: “This is the only inexpensive Wort SG to be corrected. The only other corrected refrafractometers in existence are the BREWfractometer and the BREWfractometer Extreme.”
Refractometers can be used to measure gravity throughout the brewing process. You can also estimate the alcohol content of your beer if you forget to take an OG with the use of a refractometer and a hydrometer.

I recently picked up these transfer pippettes. They are a whopping 300 mm/11.8″ Long. After using these for one beer, I can tell you that they are long enough to grab a refractometer sample from a 5 gallon batch in a Speidel 7.9 Gallon Fermenter.
