HI 93745

Chlorine/pH/Iron LR/Hardness

Light Source Light Emitting Diode @ 555 nm

Method For pH, Phenol red method. The reaction be-

tween pH and the reagent causes a red tint in

the sample.

For Chlorine, adaptation of the EPA recom-

mended DPD method 330.5. The reaction

between chlorine and the reagent causes a pink

tint in the sample.

For Iron, Adaptation of the TPTZ Method. The

reaction between iron and the reagent causes a

blue tint in the sample.

For Hardness, adaptation of the Standard Meth-

ods for the Examination of Water and

Wastewater, 18

th

edition, Calmagite/colorimet-

ric method. The reaction between hardness and

reagents causes a maroon tint in the sample.
