Capteur d''ammonium NH4+ nData

Le NH4+ (Ammonium) est un cation formé par l’addition d’un proton d’hydrogène d’Ammoniac (NH3). C’est la réaction de l’ammoniac et de l’acide de Bronstef qui génère l’ion d’Ammonium. La quantité d’Ammoniac générée dépend du pH, de la température et de la concentration de sels dissous dans l’eau.

Ammonia Sensitive Sensor (201040) JUMO

Applications. This probe is used to measure ammonia (NH3) in aqueous solutions. In an aqueous solution, ammonia is in a pH dependent balance with ammonia ions (NH4+Ionen). If the NH4+ ions are transformed into ammonia by the addition of a caustic solution, the probe will record the resulting ammonia. NH4+ ions as such will not be recorded.

Ammonia, Nitrite and Nitrate Probes? Sensors Arduino Forum

6/5/2021· Hello, I am looking for probes for determining the amount of ammonia, nitrite, and nitrate present in a liquid. Specifically, I''m looking for something I can use to monitor (not adjust, just monitor) the chemical status of my fish tank. Googleing hasn''t found me anything but the MQ137 which is a gas sensor for ammonia, not liquid.

pH in Fish Farming | Yokogawa France

pH is important in aquaculture as a measure of the acidity of the water or soil. Fish cannot survive in waters below pH 4 and above pH 11 for long periods. The optimum pH for fish is between and 9. Fish will grow poorly and reproduction will be affected at consistently higher or lower pH levels. The Effects of pH on WarmWater Pond Fish.
