Refractometers are specialist environmental test and measurement devices used to measure the angle of refraction - the extent to which light changes direction when passing through a translucent substance such as an aqueous solution. Refractometry is a widely used technology because this angle can be used to accurately assess the concentration of any .Refractometers. Refractometers are optical instruments used to measure the refractive index of liquids, gases, and translucent solids. Refractive index, also called index of refraction, is the angle that a ray of light bends when passing from one medium into another. The refractive index can provide information for us about the behaviour of light.
1. Refractometry. 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. When calibrating the refractometer, you need to make sure that you use a reference solution that is suitable for your particular instrument. For instance, if you are using a honey refractometer with a reduced Brix scale, such as 90-60 Brix (or 10-30% water) which is common for honey refractometers, you may have problems calibrating it accurately if your .
