Displayed value
This instrument measures the refractive index of a liquid and displays the converted value in "Brix", which is a percentage measurement of sugar in water. The concentration of a subsatnce other than sugar can be calculated by creating a conversion table of the desired concentration % and corresponding Brix %.
