Product Description

The DUC2-NH Ammonia Controller of the Daruifuno brand can be connected with the ammonia nitrogen electrode of the ion selection method to realize real-time online monitoring of the ammonia nitrogen value of the water quality. Because ammonia nitrogen has an impact on water bodies, the content of ammonia nitrogen must be strictly monitored in the environmental protection industry. The online ammonia controller has two SPST relays, which can be connected with other devices to control the ammonia nitrogen value. One RS485 interface, supports Modbus communication protocol, and two 4-20mA current outputs, customers can transmit data. The ammonia nitrogen controller also has the function of time and history record, which is convenient for users to query and manage data.
Equipped with NH351 ion selection method Ammonia Sensor, with self-cleaning brush, the cleaning time and cleaning interval can be set on the ammonia nitrogen controller to realize the automatic cleaning function under water. The Ammonia Analyzer is widely used in breeding, waterworks, sewage plants and other occasions that need to monitor the ammonia nitrogen content.
