Reader Tip: Dual Scale Refractometer – Corrected Scale – $19.38 Shipped

Thanks to HBF Reader Stephen for this tip!

Gravity to Brix Accuracy
Typical 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.  Check out Northern Brewer’s Refractometer Calculators.

Measure Gravity Throughout Fermentation and More: Refractometers can be used to measure gravity throughout the brewing process.  Use a Refractometer Calculator to convert brix to gravity, estimate gravity after fermentation begins and estimate alcohol content – even if you forgot to take an initial gravity reading.  That can come in handy if you’re trying to learn more about a beer you didn’t brew.
