Aumeascon AM-D-NH3N Digital Ammonia Nitrogen Sensor

图片
AM-D-NH3N    Digital Ammonia Nitrogen   Sensor Brief Introduction Th e Aumeascon AM-D-NH3N is digit al online ammonia  nitrogen sensor and with RS485 Modbus,it measure the ammonia nitrogen concentration by an ion selective electrode method.   The ammonia  ion selective electrode directly detects the ammonia  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 ammonia  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 f...
