HI-701-25 Reagents for HI-701 Free Chlorine Pocket Checker information

Hanna's extended description

The 25 pack of reagents is for use with the HI-701 Free Chlorine Pocket Checker.

These reagents follow the DPD Method in which the reaction between chlorine and reagent causes a pink tint in the sample. By simply adding the packet of HI-701-25 reagent, the reaction will take place and the HI-701 will determine the concentration from the colour that is produced. The results will be displayed in ppm (mg/L) of free chlorine. These reagents are designed to be used with samples that have an expected range of 0.00 to 2.50 ppm free chlorine.

Tip for an accurate measurement

It is important that the sample does not contain any debris.

Whenever the cuvette is placed into the measurement cell, it must be dry outside and completely free of fingerprints, oil or dirt. Wipe it thoroughly with HI-731318 or a lint-free cloth prior to insertion.

Shaking the cuvette can generate bubbles, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the cuvette.

Do not let the reacted sample stand for too long after reagent is added, or accuracy will be lost.

After the reading, it is important to discard the sample immediately, otherwise the glass might become permanently stained.
