The ARGES Ammonia Sensor by Keynes Controls is a high performance submersible sensor that has been designed to simplify the acquisition of water quality measurement parameters into any platform that supports data logging operations using digital network communications.

Each of the Intelligent Submersible ARGES Ammonia Sensor by Keynes Controls is suitable for direct connection to industry standard SDI12 Data Recorder, RS485 and MODBUS networks. The instruments can communicate directly across a MODBUS network and can be integrated into plant wide SCADA applications and to to many 3rd party PLC controllers.
