Description
Refractometer IRF-454 with illuminator and add. a scale for measuring the mass fraction of soluble solids in condensed dairy and food products (measurement range 0-85% for sucrose, the limit of the basic error is ± 0.05%)
The IRF refractometer is the most convenient instrument for determining the refractive indices of non-aggressive transparent liquids and solutions.
By choosing the IRF 454B2M refractometer, you will solve the following problems:
1. There will be no need for several refractometers with a narrower range;
2. Quality assurance is confirmed by almost a century of experience of the manufacturing plant
3. One of the most acute problems – the availability of measurement methods – was solved in favor of the IRF-454B2M refractometer, since almost all existing domestic methods and manuals are based on the use of this refractometer.
According to the measured value of the refractive indices, using conversion tables, it is possible to determine the protein content in milk, in blood serum, extract in beer, ethyl alcohol in grape wine, urine density, concentration of solutions of oils and fats in organic solvents.
Refractometers can be used in laboratories:
food industry to measure the content of sugar and solids by sucrose in drinks, fruits, berries, honey, the content of alcohol and extract in wines, vodka, beer, liqueurs, condensed milk, to determine the dry skimmed milk residue, protein in milk and dairy products, for quality control of vegetable oil, etc.;
medical institutions for determining protein in blood serum, cerebrospinal fluid, drug concentration control, urine density measurement, etc.;
chemical industry to control the concentration of various chemical and petrochemical products;
customs and other regulatory organizations for the duty-technical classification of beer, alcoholic and non-alcoholic beverages, liquid fuels, oils, chemicals and other products; scientific institutions.
