An optical instrument used to determine the concentration of sugar in grape juice.

Instrument that measures the refraction of light when it enters through a different dimension, such as from air to water or from air into a crystal.

An instrument to estimate the sugar content of grape juice by measuring the bending of light passing through it.

An instrument used to measure salinity by refraction, the amount light deflects from a straight line through a medium.

measuring instrument for measuring the refractive index of a substance

a better tool to use because it doesn't measure specific gravity but how the liquid bends light

a much more precise (and expensive) instrument than a hydrometer

an instrument that can measure the concentration of aqueous solution by measuring it's refractive index

an instrument that measures the concentration of an aqueous solution by measuring its refractive index

an instrument which measures the refractive indices of stones

an optical device that takes advantage of the fact that light passing through a liquid bends or refracts

an optical instrument that measures the degree the light has bent (the angle of refraction) as it passes through dissolved sugar

an optical instrument that measures the sucrose concentration in a sucrose and water solution

a precision bausch lomb optical instrument

a very delicate instrument

any of various instruments used to measure the refraction of a substance or medium.

An instrument designed to measure refraction (bending of light rays) of liquid supplements to determine if separation of components has occurred.

Apparatus used to measure the refractive indices of gems.

It is the instrument for measuring the refraction of light entering through a different dimension, like from air to water or from air into a crystal.

Used to measure the soluble solids content of extracted honey.

An instrument for identifying, quantitizing and/or measuring substances by means of their characteristic refractive index or dispersion.

An instrument which measures the bending (refraction) of light through a liquid. It can be used to measure the salinity of water.

An instrument used to measure the refractive index of solids and liquids. Several types exist, the most common being the Abbe refractometer. Learn more about Refractometer...

Small hand-held device that can be used for determining how concentrated or dilute a urine sample is (a measurement referred to as urine specific gravity).

A device that determines coffee's soluble solids by measuring the increased light refraction (separation into color bands) caused by adding coffee flavoring material to water.

(Fruit Juice) A device that, by defracting light, indicates the level of sugar in the solution.  This is measured in terms of degrees Brix.

An instrument designed for measuring a refractive index. In the vineyard, this index is sugar, hence the instrument measures sugar content found in grape must. The term generally used for sugar content is brix.

An optical instrument that measures the refractive index of a fluid. When used with metal working fluids, the refractometer aids in the determination of product concentration.

A refractometer is a device that measures the refractive index of a gemstone.

A refractometer is an optical instrument that is used to determine the refractive index of a substance or some physical property of a substance that is directly related to its refractive index. Certain types of refractometers can be used for measuring gases, liquids, and even transparent or translucent solids such as gemstones.
