The JBL pH Test-Set Special is designed for the accurate measurement and routine control of the pH-value in freshwater within the relevant range of 6.0 -7.6, and above all for the control and the adjustment of CO2-fertilization with the JBL PROFLORA CO2-system. The compensation method developed specially by JBL allows precise and reliable results to be obtained even in moderately discoloured aquarium water, e.g. caused by peat filters and disease treatment.
