Description:

Digital ammonia nitrogen sensor, no reagents required, green and pollution-free, can be monitored online in real time. Integrates ammonium ions, potassium ions (optional), pH and reference electrodes, automatically compensates for potassium ions (optional), pH and temperature in the water. Can be directly installed, convenient and quick. The sensor is equipped with a self-cleaning brush to prevent microbial attachment, making the maintenance cycle longer and having excellent reliability. RS485 output, supports Modbus protocol, easy to integrate.
