A new method of managing the discretization of the scale in a mobile differential refractometer

The necessity of developing a new method for managing the discretization of the scale in a mobile differential refractometer has been justified. The implementation of this method is necessary to expand the functional capabilities of  the developed mobile differential refractometer (providing a measurement mode of the refractive index of a liquid medium ranging from 1.23 to 2.63 with an error of 0.0001). All existing liquid media and their mixtures worldwide fall  within this measurement range. When using other models of compact and mobile refractometers for express control, such a measurement range of n cannot be provided. Within the range of change of n from 1.23 to 2.63, a new  management method has been implemented, which ensured a measurement error of 0.0001. Studies of various media have been conducted, confirming the adequacy of our development.
