The INFRASKAN 4200 analyzer has been tested at the D.I. Mendeleev VNIIM, entered into the unified State Register of measuring instruments under No. 83050-21. All manufactured devices undergo primary verification and have the appropriate certificate. Analyzes a wide range of quality indicators (protein, moisture, quantity and quality of gluten (IDC), fat/oil content, water absorption capacity, acid number, peroxide number, m.d. phosphorizing substances, etc.) Is calibrated to assess moisture and protein in whole grains (wheat, barley). The cuvette compartment for the analysis of bulk, liquid and pasty products allows to analyse liquid vegetable oils without the use of additional devices. The built-in whiteness module allows to determine the whiteness of the product simultaneously with other quality indicators (moisture, protein, amount of gluten). A wide spectral range (400-2500nm) provides measurement of the zonal reflection coefficient to determine the whiteness of flour in accordance with the GOST 26361-2013 methodology. It is possible to calculate the amino acid composition of feed components. To organize the work of analyzers in the ECANET network, the INFRASCAN-4200 analyzer can be used as a server for storing and transmitting data. The remote access mode allows to remotely update existing calibrations, install additional calibration models and develop new calibration models for new products, as well as make adjustments to technical settings if necessary.
