Refractometers are used in the food industry to monitor the concentration of dissolved solids in aqueous (water) solutions. Popular applications for refractometers include: condensed skim milk, whey, brines, soft drinks, juices, and coolants such as glycol.
Here's how a refractometer works: simply place a drop of the solution on the prism, lower the cover and look through the eyepiece. Solids will be indicated by a distinct line across an illuminated scale. Scales are often graduated in Brix (percent of dissolved glucose). Although this scale does not directly indicate the percent dissolved solids by weight of the product being measured, the result does give the relative concentration of dissolved solids compared to other similar solutions.
