Daruifuno's online ammonia nitrogen controller is a digital instrument. It can be connected with the digital ammonia nitrogen sensor of the ion selection method to realize real-time monitoring of the ammonia nitrogen value of the water quality. The Ammonia Controller is widely used in water treatment plants, sewage plants, industrial production processes, etc., where ammonia nitrogen content needs to be monitored. The ammonia controller has two SPST relays for control system and clean control. It has two 4-20mA current output and a two-wire RS485 interface, support Modbus protocol. The ammonia controller can display NH4-N and pH values at the same time.
