Ammonia Nitrogen Water Quality Automatic Analyzer (Salicylic Acid Spectrophotometry)

  • Description:The C310 Ammonia Nitrogen Water Quality Automatic Analyzer is a product independently developed by BESCIENT TECHNOLOGIES. It utilizes the salicylic acid sodium colorimetric method to measure the ammonia nitrogen content in water, including both surface water and wastewater. Under alkaline conditions and in the presence of a catalyst, ammonia nitrogen, which exists in the form of free ammonia or ammonium ions, reacts with salicylate to form a colored complex. The analyzer determines the ammonia nitrogen concentration based on the intensity of the color of this complex. The principle employed by the instrument complies with the "Water quality - Determination of ammonia nitrogen - Salicylic acid spectrophotometry" (HJ 536-2009) set by the Ministry of Ecology and Environment of the People's Republic of China. Factors such as excessive calcium and magnesium ions, residual chlorine, or turbidity may interfere with the measurement. Depending on the complexity of the on-site testing conditions, corresponding pretreatment systems can be optionally equipped.

● The instrument is small, easy to transport, flexible to install, and can be installed by one person

● Sampling using a peristaltic pump avoids the high failure rate of piston pumps

● The use of imported multi-way cut-off valve systems avoids the high residuals caused by the use of series valves

● Platform and modular design, easy to maintain and quickly repair, with more than 95% of the modules being universal

● The entire piping system is made of corrosion-resistant materials and is designed for forward maintenance, which reduces the failure rate, maintenance requirements and extends the service life

● Networked quality control function, remote standard sample verification, remote monitoring of instrument status and remote online software upgrades

● Low reagent consumption, reagent level monitoring and early warning, prompt customer to replace reagents

● Automatic/manual/network remote measurement, cleaning and calibration

● Fault alarm, reagent level warning, power-on self-check, power-off protection

● Imported touch screen, Chinese interface display, and perfect user rights management

● Support 4-20mA, RS232, RS485 communication interfaces and MODBUS communication methods


It is widely applied in river assessment sections, lakes, reservoirs/water sources, hydrology, and sea inlet monitoring for stationary construction station water quality online automatic monitoring.
