A saccharimeter measures the concentration of sugar in a solution making it an important instrument in food and beverage industries. Saccharimeters typically work by passing light through sugar in a solution and taking measurements of the sugar’s refractive index. While they have been around for quite some time, modern saccharimeters are automated and offer high degrees of accuracy not found in their earlier counterparts. Things to consider before purchasing include the types of sugars that can be measured, sample size, accuracy, and price.
