trodeks’s RFH Series refractometers areinstruments that determine theconcentration of an aqueous solution bymeasuring its refractive index. All waterbasedsolutions can make light bend. Thebending of light increases at a rateproportional to the increasing solutionconcentration. The handheld refractometeris a precise optical instrument. It is small,light, needs only a few drops of solution totake a measurement and is very userfriendly. Refractometers are usedthroughout the food, agriculture, chemical,and manufacturing industries. Our analogand digital refractometers are among thefinest optical instruments in the world.Weoffer a complete line of refractometers thatare suitable for all applications: Brix (BrixScale = number of grams of cane sugardissolved in 100 ml of distilled water),alcohol, propylene glycol, protein in serum,salinity, specific gravity, industrial fluids,refractive index (nD), along with manyother scales that provide the user withlimitless flexibility.
The RFH101 thru RFH107 and theRFH112 thru RFH114 are ideal formonitoring sugar concentrations in foodsand beverages. Some commonapplications are controlling ripeness of fruitin the field and measuring fruit juices, wine,honey, soft drinks, and industrial fluids.The RFH200 Series is ideal for themeasurement of salinity, saltwater, andbrine, and for food processing and canningapplications.
The specialty refractometers have a widerange of applications, from ethylene andpropylene glycol to proteins.
