Temperature compensation: The sugar refractometer uses a temperature compensation design to overcome temperature changes. When the ambient temperature changes (0-30 C), the sugar meter can automatically adjust the temperature to the optimal temperature of 20 C for measurement. Measuring range: The measuring range is 0-80%, suitable for jam, syrup, liquid sugar and other products with more sugar content, used to determine the sugar content of sugar, food, fruit, honey drinks and so on. Principle: According to different concentrations of liquid, there will be different refractive indices. Used to measure honey, condensed milk, vegetable oil, fruit syrup. The sugar content of jam is determined by determining the sugar content of honey, juice, drinks, wine, beer, etc.
