Usage: It is suitable for measuring honey, speech, vegetables, condensed milk and vegetable oils, sweets (syrup), fruit jam, molasses and the concentration of beverages, soups. Measuring range: 0-40% Brix (sugar content), resolution: 0.4% Brix (sugar content). Automatic temperature compensation (10C ~ 30C) and calibration screw ("0" calibration). Easy to use. Place 2, 3 drops of sample on the main prism, close the plate and look through the window to read the Brix value. Precision measurement: Clear dividing line (blue/white), good readability (daylight visible), adjustable eyepiece for sharpness adjustment. Calibration: Zero calibration with distilled water at 20C, automatic temperature compensation between 10C and 30C (ATC). Product Description: The refractometer is an optical precision instrument that determines the density of a liquid using the refractive index. The meter is accurate and easy to use: drop a few drops of liquid onto the prism and the density is directly readable. Easy to use: place 2, 3 drops of the sample onto the main prism, close the plate and look at the window to read the Brix value. After applying the sample to the prism, the special appearance of the reflector creates opposite light/dark fields. The boundary between the two fields marks the sugar content of the sample. Calibration: zero calibration with distilled water at 20C, automatic temperature compensation between 10C and 30C (ATC). Color: blue + gray + silver
