Ammonium sulphate vs Sugar concentration

It is possible to check the concentration of the Ammonium Sulphate in solution by using portable Sugar Refractometer. You only need to find the effective sugar concentration and then calculate the real concentration of Ammonium sulphate using form below or using chart below.

Please note, that the allowed sugar concentration from this plot can vary from 0.0% to 38.25%. All measurements outstanding this range can not be used without further correction for the determination of the Ammonium sulphate concentration.
