Kyoto Electronics KEM portable refractometer RA-130 can be placed on a table and dropped into a measuring cell, or the measuring unit can be directly immersed in the sample to test the refractive index. Built in Brix% automatic temperature correction or input temperature compensation coefficient to directly display the refractive index at the user specified temperature. Capable of saving 1100 sets of measurement results and outputting infrared signals to a printer or computer.

Main features:

1. Measurement range: refractive index: 1.3200~1.5000nD, Brix: 0~85%.

2. Digital display of refractive index, temperature compensated refractive index, Brix, concentration, etc.

3. Three sugar conversion tables, including Brix and F42/F55 solid content of fruit glucose syrup.

4. It can store 1100 sets of measurement results, with built-in infrared output and data collection software.

5. Automatic calibration function, samples can be measured using drip or immersion methods.

6. Enter the conversion formula for refractive index and concentration, and the result will be automatically converted into a concentration value.
