Checker Nitrites (up to 200 µg/L) HI764 - HANNA
Description
"Le" translates to "The" in English. If you provide more of the text, I can help translate it further for you. Hanna Ultra Low Scale Nitrite Checker® for seawater is a good compromise between the choice of simple chemical test kits and professional quality instrumentation.
Chemical test kits have limited accuracy and resolution because they are based on distinguishing color differences perceived by the human eye. Professional-grade instrumentation incorporates a light source consisting of an LED or tungsten lamp with a filter and a light detector to accurately determine the absorbance and concentration of ions.
Professional tools offer superior resolution and precision, but they can cost hundreds of euros. The Checker® Hanna For Nitrite Ultra Low Scale for seawater, a fixed-wavelength LED source and a silicon photoelectric cell are used to ensure the accuracy of professional instrumentation at the affordable price of a chemical test kit.
Recommendation
The nitrification process involves the biological oxidation of ammonia (ammonium ions) into nitrites, followed by the oxidation of nitrites into nitrates. The first step of this two-step process is carried out in an aquarium by nitrifying bacteria.
During this rapid process, ammonium levels decrease while nitrite levels increase. Since nitrites are as harmful as ammonia, nitrite levels must be kept very low. A good biological filter should be able to maintain low nitrite levels.
Additionally, if tap water is to be used for an aquarium, it is recommended to check the levels of phosphates, silicates, ammonia, nitrates, nitrites, pH, and alkalinity.
To start measuring, you must first reset the counter with a water sample. Then add the reagent. Finally, place the cuvette in the Checker®, press the button, and read the result. It's simple.
The shape of these Checkers® fits perfectly in the palm of your hand and allows you to store it in your pocket. The LCD screen is large and easy to read. The automatic shut-off feature ensures that the battery will not drain if the instrument is left on.
