The universal optical method for condition control of flowing medium

Abstract

In the article peculiarities of determination of dissolved substances concentration change in flowing liquid medium by measuring its refractive index with refractometer are considered. The measuring results of different media refractive indices are presented. The investigations of their refractive index dependencies on different factors (temperature, concentration, etc.) are carried out. The capabilities of refractometer applications for flowing medium state control at light-shadow borders displacement from refracted laser radiation are showed.
