RS485 Circulation Type Ion Sensor , IP68 Digital Ammonia Sensor

Online ammonia nitrogen sensor, using ion selective electrode method to measure ammonia nitrogen concentration. The ammonium ion selective electrode directly detects ammonium ions in the water environment to determine the concentration of ammonia nitrogen. Use a pH electrode as a reference electrode for better stability. The ammonia nitrogen concentration is easily interfered by potassium ions during the measurement process, and potassium ion compensation is required.

The digital ammonia nitrogen sensor is an integrated sensor composed of ammonium ion selective electrode, potassium ion (optional), pH electrode and temperature electrode. These parameters can mutually correct and compensate the measurement value of ammonia nitrogen, and realize the measurement of multiple parameters at the same time.

• External surface of the sensor: Wash the external surface of the sensor with tap water. If debris remains, wipe it with a moist soft cloth.
• Check the cable of the sensor: The cable should not be tight during normal work, otherwise the internal wires of the cable will be easily broken and the sensor will not work properly.
• Sensor storage: When the sensor is not in use, you should fasten the black plastic cap and check whether the sponge inside is wet. If it is not wet enough, please add 3mol / L potassium chloride solution and let the electrode be stored in the solution with potassium chloride.
