Every language version includes a non- authoritative translation. Developed for a wide range of applications, from checking the sugar concentration in beverages or the hydrocarbon content in motor fuels, the METTLER TOLEDO Portable Refractometer Line returns accurate and precise results within seconds, displayed in the measurement units needed.

A refractometer is a laboratory or field device for the measurement of an index of refraction ( refractometry). Abbe refractometers are named after Ernst Abbe, who invented the first refractometer in the 19th century. The meter uses the methodology from the ICUMSA Methods Book ( International Commission for Uniform Methods of Sugar Analysis). KRÜSS support your quality assurance. If white light were used in the simple Abbe' refractometer optics shown in Figure 2, dispersion would result in the light and dark borderline being in different places for different wavelengths of light.

Looking to have your measurement’ s data transfer directly to your Bluetooth device? The most widely used wavelength of light for refractometry is the sodium D line at 589 nm. 1 Follow the instructions in the operating manual Carefully read through the operating manual even if you have prior experience with KERN refractometers. Digital Abbe refractometer The measured refractive index or Brix as well as the temperature readings are numerically displayed simultaneously as the boundary line of refraction is being brought into the crosshairs.

Its wide range and portability allow for many different uses and applications. Variability in ºBrix readings as a result of solution temperature. Abbe refractometer part numbers.

Refractometre d abbe instruction manual. 75) and the refractometer is designed to be used with samples having a refractive index smaller than that of the refracting prism. With the new prism, the field of view is brighter than the predecessor model ( DR- A1), making it easier to measure inhomogeneous.

Introduction Congratulations on the purchase of your new Reichert Mark III transmitted light refractometer. Utilisation d' un réfractomètre et conversion. This manual describes the proper operation and care of this state of the art instrument. Positioned at the base of the unit, the RFM300- M’ s fan is designed to be protected from harsh environments, whilst still being easily accessible for maintenance. Si vous prenez des mesures multiples, sécher le réfractomètre après chaque mesure avec un chiffon de coton doux.

Food and Drug Administration ( FDA) and state and local regulatory agencies. They are designed for the rapid and accurate determination of fluid concentrations. Refractometers measure refractive index, which is the optical characteristic of a substance and the number of dissolved particles in it. 2 Though the appearance of this instrument is radically different from their previous instrument, the basic instrument remains the same.

Ited into a well that allows a light- emitting diode ( LED) to reflect light. Instruction Manual PA201, PA202, & PA203 The MISCO Palm Abbe refractometers are advanced fourth- generation handheld digital refractometers that put laboratory precision in the palm of your hand. Or Refractive Index) is read from a scale seen though the eyepiece of the refractometer. By very simple operation that needs only to set the boundary line of refraction at the cross hairs, this refractometer. Its dimensions are 19. The Abbe 3L was introduced by Bausch and Lomb in 1956 2 " Any instrument of the Abbe type consists of ( a) a refracting prism system ( b) an appropriate scale, ( c) a compensation system consisting of Amici prisms which permit the use of white light, and ( d) a telescope with crosshairs which permit the borderline of total reflection to be observed.

The MA871 is an optical instrument that employs the measurement of refractive index to determine the. 1 Instruction manual CD- ROM 55- 300. 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. 1 Mains lead see below for part number - Calibration Tables see below for part number. Apart from exceptional cases, white light is used; the refractive indices so obtained.
4 are applicable only to the REICHERT ABBE MARK II Plus Refractometer. With the AR the evaluation of the measurement takes place digitally and with the AR4 the measured value is then read via an eyepiece.
