Dual Scale Refractometer with ATC
Dual scale refractometer with ATC (Automatic Temperature Compensation). Measures 0 to 32% Brix and 1.000 to 1.120 Gravity.
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! 🙂
