What Is an Ammonia Meter?
An Ammonia Meter Is a Device to Measure the Amount of Ammonia in Water
Ammonia Meters are devices that measure the amount of ammonia in water.
Ammonia Meters are used to analyze industrial wastewater and the amount of ammonia in rivers, lakes, and seawater, as ammonia is a compound that is restricted from being released into rivers as wastewater.
Ammonia Meters Are Fitted With Electrodes
Ammonia Meters are equipped with electrodes to detect ammonium ions. The electrodes must be cleaned after each use, as contamination of the electrodes can cause fluctuations in readings. In addition, the electrodes for ammonium ions and the comparison electrode are consumables and must be replaced periodically.
Applications of Ammonia Meters
Ammonia Analysis of Wastewater and River Water
Ammonia is a compound whose discharge into the environment is restricted. Therefore, Ammonia Meters are used to control the amount of ammonia contained in industrial effluents and for environmental analysis of rivers, lakes, and seawater.
The small size of the Ammonia Meter makes it possible to collect wastewater samples on site for simple on-the-spot analysis.
Also Used in the Design of Ammonia Decomposition Processes
Ammonia Meters are also used in sewage treatment plants and wastewater treatment plants that decompose and treat ammonia.
Ammonia Meters are used to measure the amount of ammonia in wastewater before and after biological treatment to control the amount of ammonia and to design optimal processes.
Features of Ammonia Meters
Ammonia Meters Are Equipped With a Membrane and Electrodes
An Ammonia Meter is a device that quantifies the amount of ammonia from the amount of ammonium ions in water. The amount of ammonium ions is calculated from the potential difference between an electrode containing a membrane that selectively transmits ammonium ions and a comparison electrode.
Since potassium ions, which are also cations, act as interferents for the ammonium ion electrode, the Ammonia Meter is also equipped with a potassium ion electrode for compensation.
Check the Electrode Surface for Contamination Before Use
Ammonia Meters are used to measure aqueous solutions containing a variety of substances, such as river water, industrial wastewater, and sewage. Therefore, if the Ammonia Meter is immersed in a sample for a long period of time, contamination will accumulate on the electrode surface.
The electrode must be replaced periodically because the accumulation of contaminants causes fluctuations in the measured potential difference. Some devices have a built-in ultrasonic oscillator, which can remove dirt and scale from the electrode surface.
Ammonia Meters are also available that constantly immerse the electrode in a sample solution and output data on ammonia levels, as monitoring of ammonia levels over time is necessary for some applications.
