Before the aluminum anodizing, aluminum surfaces are cleaned in etching baths. To maintain surface properties, online monitoring of bases (NaOH, etc.), acids (H2SO4, HNO3, HF, H3PO4, etc.) and aluminum is required. This is best achieved by titration with Process Analyzers ADI 2045TI and ADI 2016, depending on single- or multiparameter needs..
