Digital Refractometer For Brix DRB series Digital Refractometer for Brix are developed for working with sugar related liquids ( fruit juices, soft drinks wine) , help monitor and control sugar concentrations in foods and beverages. Whether users are checking the “ ripeness? of fruit in the field, verifying product quality after harvesting, or controlling concentrations during processing and packaging, refractometers provide critical information to ensure product quality. But, it is also commonly used for controlling the concentration of various industrial fluids cutting lubricants and flux rinsing compounds) . This instrument is equipped with an Automatic Temperature Compensation System making it ideal for field use. Product Specification Model Scale Range Div. Accur.
