Beerbrew Brix Refractometer for Homebrew Beer Wort SMARTSMITH Dual Scale Automatic Temperature Compensation 0 32% Specific Gravity Hydrometer with ATC

BREW BEER RERACTOMETER Specifications: Measurement range:Brix(0-30%)/SG(1.000-1.130) Accuracy: ±2% Operating Temperature: 32 - 122 °F Package Dimension: 8.03"×2.99"×2.13" Net Weight: 7.2 oz Wide Application. 1 Measure progress of the fermentation 2.The amount of sugar present as well as alcohol concentration in grapes measure 3.The Brix% is quite close to °P, and they can be regarded as equal. 4.The connection between °P with S (Specific Gravity): °P = (463-205*S)*(S-1); S = (°P/(258.6-227.1*°P/258.2))+1 Features: No waste:2 drops to get the accurate reading Automatic Temperature Compensation (ATC) Dual scale display(SG and Brix) Easy 2 steps Calbriation Aircraft Anti-Corrasive Alumnium Body Amazing Accuracy <2% Package Includes: 1×Beer Brix refractometer 1× Calibration screw 1xCleaning Cloth 3x 3ml droppers 1×User’s manual Kind Reminder: 1.If the refractor is being used for the first time or has not been used for a month or more,  calibrate it to 0 with distilled water. 2.Calculation Formula: Brix=sugar / (water + sugar) Eg. Add 20 grams of sugar into 100 grams of water,so brix in this case is 20/(100+20) = 16.6%
