Application field

The instrument is widely used in industries such as environmental surface water, municipal sewage, aquaculture water bodies, and industrial process water

Product Principle

The determination principle of ammonia nitrogen is based on the relationship between the activity and concentration of ions in electrolyte solutions. It usually consists of two sensors: the working sensor and the reference sensor. A working sensor is a sensor that selectively reacts with the ion being measured, while a reference sensor provides a stable potential as a reference. Work sensors are typically coated with a selective membrane that can react specifically with specific ions. When the tested ion reacts with the selective membrane, a potential change occurs, and the concentration of the ion can be determined by measuring this potential change.
