Detect biological activities in water systems such as rivers, reservoirs, bays. The ARGES CDOM/FDOM Sensor by Keynes Control is a single-channel instrument that can detect and report CDOM levels in the range of 0 - 1000 QSU and temperature in Degrees Celsius. The sensor has been designed to be used as a stand-alone laboratory instrument, as part of a multi-parameter device inside a Keynes Controls SONDE, and can be connected directly into a plant-wide SCADA system using the in-built MODBUS protocol. The SDI12 and RS485 digital networks enable the sensors to be directly connected to Web based data loggers, Wi-Fi and Local Area Networks.
