Method
For pH:
Phenol red method. The reaction with the reagent causes a red tint
in the sample.
For Chlorine:
Adaptation of the EPA, DPD method and Standard Method
4500‑Cl G. The reaction between chlorine and the reagent causes a pink tint
in the sample.
For Cyanuric Acid:
Adaptation of the turbidimetric method. The reaction
between cyanuric acid and the reagent causes a white suspension in the
sample.
For Iodine:
Adaptation of the EPA, DPD method. The reaction between iodine
and the reagent causes a pink tint in the sample.
For Bromine:
Adaptation of the EPA, DPD method. The reaction between
bromine and the reagent causes a pink tint in the sample.
For Iron LR:
Adaptation of the TPTZ method. The reaction between iron and
the reagent causes a violet tint in the sample.
