Optech portable refractometers

Simple and precise instruments to analyse liquids and their dissolved solid content.
Except for two models, all Optech portable refractometers are equipped with an automatic temperature compensation device (ATC).
Supplied in plastic box with imitation-leather case and instruction manual.

RA-130 measures the refraction index (RI) and related measures

(nD, Brix and three different conversion tables for sucrose and isomerized sugar HFCS42, HFCS55).
Tables of planned concentration are available, such as 10 temperature coefficients freely definable and storable by the user for automatic compensation.
The measure can be carried out by immersing the cell in the sample or placing a drop of sample on the prism.

Other features:

  • Calibration with distilled water
  • Data memory:for 1100 results
  • Data transfer to PC via IR port
  • Power supply: 2×1,5 V batteries
