BH-485-NH is digital online ammonia nitrogen sensor and with RS485 Modbus,it measure the ammonia nitrogen
concentration by an ion selective electrode method. The ammonium ion selective electrode directly detects the
ammonium ion in the water environment to determine the concentration of ammonia nitrogen. Use a pH electrode
as a reference electrode for better stability. The concentration of ammonia nitrogen in the measurement process is
easily interfered by potassium ions, so potassium ion compensation is required.
The digital ammonia nitrogen sensor is an integrated sensor that is composed of ammonium ion selective electrode,
potassium ion (optional), pH electrode and temperature electrode. These parameters can mutually correct and
compensate the measured value of ammonia nitrogen, and meanwhile achieve the measurement for multiple parameters.
