Reagents for HI-755 Alkalinity Pocket Checker
Liquid reagent for 25 tests for use with the HI-755 Alkalinity Pocket Checker.
The HI-755-26 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Marine Alkalinity Checker® HC. These reagents follow the Colorimetric Method in which the reaction causes a distinctive range of colours from yellow to green to blue to develop. By simply adding the solution of HI-755-26 to the sample, the reaction will take place and the Marine Alkalinity Checkers will determine the concentration from the colour that is produced. The results will be displayed in ppm of CaCO3. These reagents are designed to be used with samples that have an expected range of 0 to 300 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 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
