Dual Scale Refractometer – $21.85 Shipped + 12″ Pippettes

This highly rated dual scale refractometer is selling for $16.86.  Shipping is $4.99.  It reads in both Brix and Gravity.

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.  Check out Northern Brewer’s Refractometer Calculators.

I just picked these transfer pippettes up.  They are a whopping 300 mm/11.8″ Long.  The long length should allow me to pull refractometer samples, for most beers, directly from my fermenter.  You get 100 for $15.40.  That’s 15.4 cents each.
