Squeeze the pump to create a vacuum and then release to draw the liquid in. Cleaning is as simple as operating the pump a few times in water. The prism chamber can also be opened up for removal of persistent residues.

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 substance other than sugar can be calculated by creating a conversion table of the desired concentration % and corresponding Brix %. Contact ATAGO for further details.
