    Description

    Refractometer IRF-22
    Description and application of the refractometer IRF-22:
    The IRF-22 refractometer is intended for direct measurement of the refractive index of liquid and solid bodies in the range 1.3-1.7 for the D line and the average dispersion of these bodies with an error in the reading of the device obtained from multiple measurements and not exceeding ± 2 * 10-4 for refractive index and ± 1.5 * 10-4 for average dispersion.
    Refractometer IRF-22 can be used to quickly determine the concentration of aqueous, alcoholic, ethereal and other solutions by the refractive index nD.
