Ammonia nitrogen in water refers to free ammonia (NH) in water3)And ammonium ion (NH ₄)+)Ammonia nitrogen exists in form. Ammonia nitrogen is the most harmful form of nitrogen among all types, and is a sign of water pollution. Its harm to the aquatic ecological environment is manifested in multiple aspects.
The instrument adopts automatic control for water sample collection, reaction measurement, data processing, and data transmission, and quickly and continuously completes the entire process of ammonia nitrogen analysis in wastewater.
The instrument uses Nessler's reagent spectrophotometry to react ammonia nitrogen in the form of free ammonia or ammonia ions with Nessler's reagent to form a yellow brown complex. The color of the complex is proportional to the content of ammonia nitrogen.
◆The 7-inch LCD touch screen is easy to operate, with a beautiful and elegant interface, and rich and intuitive display content.
◆The light source adopts imported monochromatic photodiodes, which have excellent performance, energy concentration, and low power consumption.
◆Adopting high-precision injection pump, with high measurement accuracy and low reagent consumption.
