Hanna Instruments HI-753-25 Chloride Checker Spare Reagent 25 tests
The HI-753-25 are the replacement reagents for the HI-753 Chloride Checker® HC. These high-quality reagents are clearly marked with the lot number and expiry date on each packet for traceability.
The HI-753-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Chloride Checker® HC. These reagents follow the Mercury (II) Thiocyanate Method in which the reaction between chloride and the reagents causes an orange tint in the sample. By simply adding the two reagents from the HI-753-25 set, the reaction will take place and the HI-753 will determine the concentration from the colour that is produced. The results will be displayed in ppm of chloride. These reagents are designed to be used with samples that have an expected range of 0.0 to 20.0 ppm chloride.
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.
