Online ammonia nitrogen monitoring instrument for sewage discharge outlet

Online ammonia nitrogen monitoring instrument for sewage discharge outlet

Model: AME-3010

Method basis: Salicylic acid spectrophotometric detection. Measurement range: 0-50mg/L, 220V power supply, 4-20mA current output. Dimensions: Height 800 * Width 389 * Depth 306mm, equipped with a set of reagents and a self-priming pump.

Detection principle

Under alkaline conditions, using trisodium citrate as a masking agent, ammonia and ammonium ions in the water sample are storedUnder certain conditions, react with salicylate and hypochlorite ions, and detect the absorbance of the product at a specific wavelength,According to Lambert Beer's law, there is a linear correlation between the concentration of ammonia nitrogen in water and its absorbance, which can be used to determine the concentration of ammonia nitrogen in waterAmmonia nitrogen concentration.

Application Fields

This monitor is mainly used for real-time monitoring of ammonia nitrogen (NH3N) concentration in surface water, domestic sewage, and industrial wastewater.

Characteristics

lThe monitor is compact in size and easy to maintain on a daily basis;

lThe monitor adopts high-precision photoelectric measurement and detection technology, which is suitable for various complex water bodies;

lEquipped with dual ranges (0-10mg/L) and (0-50mg/L), it meets the monitoring needs of the vast majority of water quality on sitePlease. The range can also be expanded according to the actual situation on site;

lEquipped with measurement modes such as fixed-point, periodic, and maintenance, meeting the requirements for monitoring frequency on site;

lThe consumption of reagents is extremely low, greatly reducing operation and maintenance costs;

lMultiple communication methods such as 4-20mA, RS232/RS485, etc., meet the communication requirements of the monitoring instrument on site;
