BulletPoint1 : ABBE Refractometer Applications of the instrument This instrument can widely be used in petroleum, chemical, pharmaceutical, sugar refining and food industries, as well as in related colleges, universities and scientific research institutions for measuring the refractive index n of transparent, subtransparent liquid o r soli d subsance . This D instrument can also be used to measure the Brix(BX) of the sugar solution, and correct the affect of temperature on the Brix automatically. In addition, this instrument can display the temperat ure of the sample.
BulletPoint2 : Digital Abbe Refractometer Principle The operational principle of the ABBE refractometer for measuring the refractive index of the transparent or subtransparent substance is based on the measurement of the critical angle. The observation system composed of the visual telescope unit and dispersion correction unit can be used to aim at the dividing line between the bright area and the dark area,that is to aim at the critical angle. The angle-digit conversion unit can be used to convert the angular magnitude into digital magnitude, which will be sent into the microprocessor system for being data-processed. Then. The refrac- tive index of Brix of the sample being measured will.
BulletPoint3 : Digital Lab ABBE Refractometer Operating procedure When the power switch¡°POWER¡± (4, see fig. 2) is pressed, the illuminating lamp in the light-gathering illuminating unit (10) lights up; and at the same time, the display window (3) displays ¡°00000¡± a few seconds later. ò. Open the refracting prisms unit (11), and remove the mirror-cleaning paper. Which is put in between two prisms when the instrument is idle to prevent the hard the particles possibly remaining on the prisms from damaging the working surfaces of the prisms. Only single-layer mirror-cleaning paper is needed.
BulletPoint4 : Digital Abbe Refractometer Calibration of the instrument The instrument should be calibrated periodically, or when the measuring data is under su spicion,the instrument may also be calibrated. Whe n making t he calibrat ion, dist illed water or glassstandard block should be used. If ther e is an error between t hemea suri ng data and the standardone, you may use an inner-hexagon spanner, let it go into the sma ll hole of the dispersioncorrection hand-wheel ( 2 ) ,and rotate the insid e screw carefully, so as to make the cross lin on thedivision plate move up and down(see fig.5). Then perform the measurement again until themeasuring data meets the requirement.
BulletPoint5 : Abbe Digital Refractometer When the sample is the standard block, the measuring data should conform to the specified dataon the standard block. If the sample is distilled water, the measuring data should coi ncide with the data listed in the following table.
