Functionality: fully functional - the lens of the lens and viewfinder are clean, the viewfinder's visibility is good - without distortion, the focus and aperture work smoothly and pleasantly. The picture is clear, bright.
The IRF-464 milk refractometer is designed to measure the refractive index of dispersing liquid media. It can be used to determine the percentage of protein in milk by the difference in indications for milk and whey on a protein scale, as well as other non-fat components of milk and liquid dairy products.
The IRF-464 refractometer allows you to quickly and reliably determine the content of protein and solids in milk (SOMO) and its products without the use of expensive chemicals, which makes it possible to widely use the device for certification of dairy products, as well as in cheese making.
The refractometer is used in the dairy industry, agriculture, catering, as well as in research institutes.
In addition, the IRF-464 refractometer can be used in brewing to "determine the alcohol and actual extract using the refractometric method." According to the formula, these two parameters calculate the solids in the initial wort without the distillation process.
Technical characteristics portable refractometer IRF 464:
Range of measurement of refractive indices nD - 1,325 - 1,360;
The range of measurements on the scale of protein - 0 - 15%;
The price of dividing the scale of the refractive index nD is 5 × 10-4;
The division value of the protein scale is 0.1%;
The limit of permissible basic error in the refractive index nD is ± 2.5 × 10-4;
The limit of permissible basic error according to the PROTEIN scale is ± 0.1%;
