Fully automatic refractometer RA-620/RA-600

Automatic refractometer RA-620/RA-600 Terminology and definitions:

Refractive index: The ratio of the speed of light in air to the speed of light in the object being measured, or the ratio of the sine of the incident angle of light passing through the object from air to the sine of the refracted angle, under the conditions of sodium spectrum D-line and 20 ° C.

Soluble solids (Brix Brix): Measure the refractive index of the test solution at 20 ° C using a refractometer, and directly read the content of soluble solids using a conversion table or refractometer between refractive index and soluble solids content. The soluble solid content determined by refractometer method, under specified preparation conditions and temperature, has the same refractive index as the analyzed sample in the concentration of sucrose in the aqueous solution, expressed as a mass fraction.

The main features of the fully automatic refractive sugar analyzer RA-620/RA-600 are:

1. A Chinese color touch screen that displays refractive index, temperature, sugar content, alcohol content, or concentration simultaneously.
2. Built in automatic Peltier temperature control, fast heating and cooling speed, lightweight appearance, and easy operation.
3. Use durable LED light source with a long service life, and the prism is made of sapphire that is wear-resistant and easy to wipe.
4. Place the measuring cell in front of the instrument for easy sample addition and to prevent sample contamination and damage.
5. Total reflection accurately measures turbid or dark samples, and special covers can stably test volatile samples.
6. The measurement results can be automatically converted into user-defined units, such as Brix, Alcohol, or Concentration.
7. Automatic calibration verification and inspection, error detection, record history to ensure the accuracy of measurement data.
8. Automatically store calibration records and results, and can be output using a USB flash drive, printer, or Ethernet.
9. It can be combined with a densitometer to measure both density and refractive index simultaneously. Or connect multiple sample automatic injection devices.
