Hanna Instruments HI-715-25 Reagents for HI-715 Ammonia Medium Range Checker HC
HI-715-25 Reagents for HI-715 Ammonia Medium Range Checker HC
The HI-715-25 are the replacement reagents for the HI-715 Ammonia Medium Range Checker® HC.
The HI-715-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Ammonia Medium Range Checker® HC. These reagents follow the Nessler Method in which the reaction between ammonia and reagents causes a yellow tint in the sample.
By simply adding 4 drops from each bottle of the HI-715-25 reagent set to the sample, the reaction will take place and the HI-715 will determine the concentration from the colour that is produced. The results will be displayed in ppm (mg/L) of ammonia-nitrogen (NH3-N). These reagents are designed to be used with samples that have an expected range of 0.00 to 9.99 ppm ammonia-nitrogen. To convert the reading to ppm of ammonia (NH3) multiply the result by 1.214.

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.
