  • Brix Refractometer, Sugar Concentration & Refractive Index

    PA202 - MISCO Refractometer

    Dual-scale digital refractometer with scales for measuring both Brix (to 85) and refractive index (to 1.5000). Brix is a measure of sugar concentration and is used extensively in the agriculture and food and beverage industries. Refractive index is a fundamental physical property of a solution and is related to the speed light travels through it. Both the Brix and refractive index scales can be used to measure a nearly unlimited number of fluids.
