1)
The fluctuations in concentration, not the absolute value, are the determining factor
2)
Recommendation: Use as compensation electrode for potassium concentrations > 40 mg/l in the case of
simultaneously fluctuating values of ± 20 mg/l, or apply an offset in the case of non-fluctuating values.
Chloride

3)
Recommendation: Use as compensation electrode for chloride concentrations > 500 mg/l in the case of
simultaneously fluctuating values of ± 100 mg/l, or apply an offset in the case of non-fluctuating values.
