Anderson-Negele prides itself on creating sensors that are both durable and simple to configure our in-line refractometer is no exception. Commonly used in food and beverage manufacturing to assure that the concentration of a dissolved solid such as sugar is at the required concentration to meet the specification. Based on the optical principle of light refraction through varying media density the IRM creates a precise measurement of a liquids refractive index which is used to measure dissolved solids concentrations
