Important
■ Please follow the manufacturer`s recommendations regarding
the appropriate time for measuring O
treatment agent and the ideal range.
■ pH values below 6.8 also produce a yellow colouration,
so a reading of 6.8 may be incorrect.
■ pH values above 8.2 also produce a red colouration,
so a reading of 8.2 may be incorrect.
■ Water samples with low values of Total Alkalinity may give
wrong pH readings.
