Hanna Instruments-719-25 Reagents for the Hanna Instruments-719 Magnesium Hardness Checker®HC


The Hanna Instruments-719-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Magnesium Hardness Checker® HC. These reagents follow the EDTA colorimetric method in which the reaction between magnesium and the reagent causes a violet tint in the sample. When the Hanna Instruments-719-25 reagents are added to the sample, the reaction will take place and the Hanna Instruments-719 will determine the concentration from the colour that is produced. The results will be displayed in ppm of magnesium hardness as CaCO3. These reagents are designed to be used with samples that have an expected range of 0.00 to 2.00 ppm CaCO3.








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 Hanna Instruments-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.
