Digital Online NH4-N Ammonia Nitrogen Sensor By Electrode Method For Water Quality Monitoring Test
Our company's online ammonia nitrogen sensor requires no reagents, is green and pollution-free, and can be monitored online in real time. Integrated ammonium ion, Nitrate ion (optional), pH and reference electrode, automatic compensation for Nitrate ion (optional), pH and temperature in water. Can be directly installed, compared with traditional ammonia nitrogen analyzer, more economical and environmentally friendly, convenient and fast. The sensor is equipped with a self-cleaning brush, which can prevent the adhesion of microorganisms, make the maintenance cycle longer, and have excellent reliability. It adopts RS485 output and supports Modbus for easy integration.
