The PAL-BX/ACID Series (16 different models) measures sugar and acidity level in fruit juices, milk, beer, yogurt, sake, or vinegar. Each unit in this series measures both Brix (sugar level) and acidity. Unlike the traditional titration method, PAL-BX/ACID requires no costly reagent.Measurement Range: Brix:  0.0 to 60.0%Measurement Accuracy: Brix: ±0.2%; Acid: ± 0.10% (Acid 0.10 to 1.00%)Dimensions and Weight: 55(W) × 31(D) × 109(H)mm, 100g (main unit only) Automatic Temperature Compensation Range: 10 to 40°CInternational Protection Class: IP65
