CNYST Benchtop Abbe Refractometer Lab ABBE Refractometer with LCD Display Measuring Range Refractive index (nD) 1.3000-1.7000 Brix 0-100% Measuring Resolution Refractive index (nD) 0.0001 Brix 0.1%

Applications：

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 nD of transparent, subtransparent liquid or solid substance.

This 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 temperature of the sample.

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 refractive index of Brix of the sample being measured will be displayed digitally.
