Ammonia Nitrogen Sensor
Key Specifications：
✅Range 0-1000mg/L(Customisable)
✅RS485,MODBUS protocol
✅Ion electrode method
✅Easy on-site use
✅Online real-time monitoring
Online real-time ammonia nitrogen sensor doesn't require reagents, is green and pollution-free. Ammonium ion electrode, pH electrode and reference electrode are standard(potassium ion is optional), automatic pH and temperature compensation in the process of measuring ammonia nitrogen in water, so that the measurement value is more accurate. Electrodes are individually replaceable and easy to maintain.The sensor can be installed directly into water, using RS485 output, MODBUS protocol, easy to integrate.
