HI-708-25 REAGENTS FOR HI-708 NITRITE HIGH RANGE POCKET CHECKER
HI-708-25
The HI-708-25 are the replacement reagents for the HI-708 Nitrite High Range Checker® HC.
These high-quality reagents are clearly marked with the lot number and expiry date on each packet for traceability.
The HI-708-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Nitrite High Range Checker® HC. These reagents follow the Ferrous Sulphate Method in which the reaction between nitrite and reagent causes a greenish-brown tint in the sample. By simply adding the packet of HI-708-25 reagent to the sample, the reaction will take place and the HI-708 will determine the concentration from the colour that is produced. The results will be displayed in ppm (mg/L) of nitrite. These reagents are designed to be used with samples that have an expected range of 0 to 150 ppm nitrite.
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.
