0-32% Brix Scale. Accurate to +/- 0.20% Brix. Automatic temperature compensation (ATC).  Aluminum body.  Includes refractometer, calibration screwdriver, sample pipette, cleaning cloth, manual and storage case.

For me, getting a refractometer was one of those upgrades that made a lot of difference.  With a refractometer you need a sample size of two drops.  I figured that this would pay for itself in beer savings alone.  I also had just broken my hydrometer and came to the realization that hydrometers are made of breakable glass that can break! 🙂
