Description The refractometer is used to measure refractive index (nD) of liquids that are transparent or translucent and solid being the most frequently used to clear liquids. Practical applications of this instrument are very large, being an essential tool in the petroleum, oils and greases, paints, pharmaceutical, food, cosmetics, chemicals and sugar, as well as Unversity and research and teaching.ABBE Refractometers are supplied with a test piece for testing and calibration of the device and also feature a bottle of contact monobromo and naphthalene. The eyes of all the teams are dotadosde dioptric correction. MODEL 325 Laboratory refractometer to measure refractive index and sugar content (Brix). Metal construction equipment ready to be coupled to a circulation thermostat. The scale is illuminated by natural light can make the illumination incident or transmitted, depending on the nature of the sample to be measured.Increases the optical system: 2x.Increases reading system: 30xWith thermometer FEATURES: Readable scale.Range: Brix: 0-95%Refractive index: nD 1300-1700Accuracy: Brix + / - 0.25%nD: + / - 0.0005 nDThermometer scale: 0 º C to 70 º C.RS 232: Printer connection.
