IRF-454B2М refractometer has the biggest range of measured values for the refractive index and sucrose from the overall released series.

The refractometer can be used:

1. IN MEDICAL INSTITUTIONS - for determination of protein in urine, in blood serum, urine density, analysis of brain and synovial fluid, density of subretinal and other fluids of the eye. Our instrument significantly reduces the time of analysis of the protein content in the serum, when using Reiss tables, and does not require any chemical reagents for sample preparation. Our instruments allows to significantly reduce time in mass examinations of the patients.

2. IN PHARMACEUTICAL INDUSTRY can be used to analyze aqueous solutions of various drugs:

¨ calcium chloride ;

¨ novocaine;

¨ ephedrine ; glucose;

¨ magnesium sulfate ;

¨ sodium chloride ;

¨ cordiamin, etc.


· at sugar and bread making plants, confectionery factories for the analysis of products and raw materials, semi finished products, culinary products and starchy foods

· determines the moisture content of honey (up to 20 %)

· to determine the dry matter content in different worts (GOST 5900-73), "soakings",  syrup for marmalade, marshmallow, creams and cakes, "tirage" for gingerbread;

· to determine the mass fraction of soluble solids by sucrose ( Brix ) in the products of fruit and vegetable processing

· to determine the content of fat in solid foods (gingerbread, wafers or bakery products)

· concentration of salts.

Refractometers can be used in laboratories of sanitary-epidemiological control, veterinary hospital, laboratory of a medical institution, as well as metrological control.

4. WHEN SERVICING EQUIPMENT for precise determination of the volume concentration of the anti-crystallization liquid "IM", which is added to aviation fuel in an amount of 0.1 to 0.3%. Further processing of results shall be conducted according to "Methodical recommendations on the analysis of lubricant quality in civil aviation" Part II p. 159.

Experience in the use of this type refractometers in Kazan airport, Siberian Aviation Fuel-Energy Company, and others, showed that our instrument significantly reduces the time and increases the reliability of the analysis on content of "IM" liquid in the aviation fuel.

The refractometer can be supplied with or without the state verification (You can address request to the certification bodies for verification of the instrument).

IRF-454B2М refractometer is included in the State register of measuring instruments of the Russian Federation under the number 7308-94.
You can download the Certificate of measuring instrument type approval No. 8539 (valid until March 27, 2020) on this page.

State verification is confirmed by the imprint of a stamp in the Operation Manual.
