This is one of the quantitative (numeric) values used to determine if a plant product (fruit, vegetable, grass) meets the standard for harvesting. All the plantphytonutrients, vitamins, hormones and thousands of other powerful components are created within theliving plant by combining chains of sugars. table or digital refractometer or Brix meter. The refractometer uses a unit called a Brix value or score. Enter email address Refractometers are a standard piece of equipment for many agronomists and are a standard tool used in the fruit and citrus industries, measuring dissolved sugars and solids in a liquid on the "Brix" scale. Refractometry is generally speaking the measurement of refractive index and its interpretation under different starting points. Handheld Digital Refractometer. Testing the sugar content in your grass is easy. A low Brix rating in a plant will not provide the correct amount ofenergy to the person or animal that eats it; nor will a low Brix plant have the necessary medicinal propertiesthat act as wormer’s, “antibiotics”, immune tonics, antioxidants and other vital nutrients. Digital Density Meters and Refractometers like the DM40 Density Meter and the RM40 Refractometer from Mettler-Toledo allow to measure directly Brix degrees or HFCS %. When just a few drops of sap or juice are placed on the refractometers prism and held up to the light, the light passing through the sap is refracted (bent) according to the composition of that sap. Factors that contribute to good preservation are: harvesting in dry sunny weather, mature grass after ear emergence, swards consisting of perennial and Italian ryegrass, wilting. (b) A representative grass sample. A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry).The index of refraction is calculated from Snell's law while for mixtures, the index of refraction can be calculated from the composition of the material using several mixing rules such as the Gladstone–Dale relation and Lorentz–Lorenz equation With an analog refractometer, the sample is place on a cover plate and a prism and then held to the light to view the scale inside the meter.
