HHTEC Wine Refractometer 3 Scale Brix 0–32%, Oechsle 0–140 °Oe, KMW 0–27° with ATC, Professional Winemaking Sugar Tester for Grapes, Must and Wine

• Triple scale for professional winemaking: Brix (Mas sacch): 0–32%, Oechsle: 0–140°, KMW: 0–25°, Resolution: 0.2% / 2.0° / 0.5° – enables precise sugar measurement for grape must and wine production.
• Designed for wine fermentation control: Ideal for measuring grape must, monitoring fermentation and estimating potential alcohol levels.
• Accurate readings with ATC: Automatic temperature compensation from 10°C to 30°C ensures consistent and reliable results.
• Easy calibration and use: Zero calibration with distilled water at 20°C using the adjustment screw for accurate baseline measurement.
• Important usage limitation: Designed for wine-related liquids only, not suitable for distilled alcohol, honey or seawater salinity measurement.
