Nitrate Checker in seawater, narrow range HI781 Mini-photometer HANNA
Checker Nitrates HI781 - HANNA
The HI781 Checker is a portable colorimeter that uses the Beer-Lambert principle to determine nitrate concentration through colorimetry. The HI781 is specifically designed to measure low levels of nitrate in a saltwater aquarium. The scale ranges from 0.00 to 5.00 ppm (mg/L), making it ideal for the maintenance of reef aquariums.

Nitrates Checker HI781 - HANNA
Description
"Le" translates to "The" in English. If you provide more of the text, I can help translate it further for you. Hanna Checker ® for low-range nitrates in seawater (ppm) is a good compromise between choosing 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 includes a light source composed of an LED or a tungsten lamp with a filter and a light detector to accurately determine absorbance and ion concentration. Professional tools offer superior resolution and precision, but they can cost hundreds of euros.
The Checker ® Hanna For nitrates in seawater, it measures the nitrate value in ppm and uses an LED source with a fixed wavelength and a silicon photoelectric cell to ensure the accuracy of professional equipment at the affordable price of a chemical test kit.
Nitrate is a by-product of the nitrogen cycle. Excessive amounts of nitrates in a reef aquarium can promote the growth of undesirable organisms, including algae and dinoflagellates, while insufficient amounts can cause problems for SPS (small polyp stony) corals, including loss of color and the appearance of paleness.
The HI781 Checker is a portable colorimeter that uses the Beer-Lambert principle to determine nitrate concentration through colorimetry. The HI781 is specially designed to measure low levels of nitrate in a saltwater aquarium. The scale ranges from 0.00 to 5.00 ppm (mg/L), making it ideal for maintaining reef aquariums.

Le Top pour les test
Apres plusieurs mois d'utilisation sur différents modèles de la marque Hanna, je dois avouer que je suis accro à ce genre de test, produit de qualité, fiable, dans une belle boite pour le stockage, le prix est plus que raisonnable, et je trouve que cela vaut largement quelques euros de plus par rapport à des tests dit classique, personnellement je pense que ce genre de produit doit faire parti du kit de l'aquariophile soucieux de la qualité d'eau de son bac !!
