What is Ammonia Nitrogen?

Ammonia Nitrogen refers to the nitrogen present in water in the forms of free ammonia (NH3) and ammonium ions (NH4+). Generally, animal-based organic matter contains a higher nitrogen content compared to plant-based organic matter. Nitrogenous compounds in human and animal waste are often unstable and can easily decompose into ammonia.

Ammonia nitrogen acts as a nutrient in aquatic environments, potentially leading to a phenomenon known as eutrophication, which causes excessive growth of algae. It is also a major oxygen-depleting pollutant in water bodies, posing a toxic threat to fish and certain aquatic organisms.

Regarding human health, ammonia nitrogen can convert into nitrites under specific conditions. Long-term consumption of water with nitrites can result in these compounds combining with proteins to form nitrosamines, which are potent carcinogens and can be extremely detrimental to human health.

FAQS
How can I select a water quality sensor for my project?

Provide the required measurement parameters, expected ranges, water characteristics, installation conditions, and communication requirements. Yosemitech can help identify potentially suitable products and confirm technical compatibility.


How often should water quality sensors be calibrated?

Calibration frequency depends on the sensor technology, operating environment, manufacturer recommendations, and required measurement accuracy. Regular verification and cleaning may be necessary, particularly in demanding environments.


What is the difference between optical and electrochemical water quality sensors?

Optical sensors use interactions between light and the measured medium, while electrochemical sensors rely on electrical or chemical responses at sensing elements. Each technology has different advantages, limitations, and maintenance requirements depending on the parameter and application.


What types of water quality sensors does Yosemitech manufacture?

Yosemitech offers optical dissolved oxygen, COD, turbidity, pH, ORP, conductivity, ammonium, nitrate, chlorophyll, blue-green algae, and other water quality sensors, as well as multiparameter monitoring instruments.


What is a Water Quality Sensor?

A water quality sensor is a measurement device used to monitor a specific physical, chemical, or biological indicator in water. Common examples include dissolved oxygen, turbidity, pH, conductivity, temperature, and nutrient sensors.
