Product Description
Handheld Brix refractometers are commonly used in agriculture, food manufacturing, and industrial environments. Farmers use them to measure sugar levels in crops to decide when to harvest. In food and drink production, they help ensure the right mix of ingredients. In industrial use, they check the concentration of fluids used for cutting and grinding.
The RHB-18A handheld Brix refractometer is designed specifically for measuring the concentration of sugar in the liquid being tested, with a measurement range of 0 to 18% Brix and a measurement accuracy of ± 0.1%. This model is suitable for low to medium sweetness fruits (strawberries, peaches, oranges), freshly squeezed fruit juice (apple juice, pear juice), energy drinks, seasoning juices, etc.
