Fluorometers Water Quality Sensors by Keynes Controls

The ARGES range of intelligent, high performance submersible fluorometers have been designed to simplify the acquisition of water quality measurement parameters into any platform that supports data logging operations using digital network communications.

The sensors are supplied factory calibrated for immediate deployment. The sensors can be used stand-alone or as part of a multiparameter systems. Options are available for real-time and stand-alone recording.

Application Software

Sample Results ARGES pH sensor
Real-time Chloride - Conductivity chart using ARGES Sensors
Realtime results - Tryptophan, CDOM, Turbidity

The applications software enables real-time measurements to be made and displayed into a series of charts and panel meter displays.

The QLOG software that is supplied with the sensors is used to fully configure the sensors and multiparameter systems.
