Standard refractometers measure the extent of light refraction (as part of a refractive index) of transparent substances in either a liquid or solid-state; this is then used in order to identify a liquid sample, analyze the sample's purity, and determine the amount or concentration of dissolved substances within the sample. As light passes through the liquid from the air it will slow down and create a ‘bending’ illusion, the severity of the ‘bend’ will depend on the amount of substance diss… WebZEBRA OPT10 Hand-Held Refractometer Instructions ZEBRA OPT10 Hand-Held Refractometer WARNING!

WebThese digital refractometers feature an LCD, eliminating reading errors with common handheld refractometers. All models feature built-in automatic temperature compensation (ATC) which removes temperature fluctuations allowing the user to concentrate on the measurements. The compensation range is 41 to 104°F (5 to 40°C).
