BRIX - Sugar Determination By Density and Refractometry ...

Any other sugar product as sucrose can therefore not give the correct Brix value. When determining the Brix degrees on e.g. malt sugar glucose honey the obtained results are not the true Brix degree and are only relative values. Obtained Brix values on a non sucrose measurement with Density meter or Refractometer can therefore not be compared.
