Intelligent Water Quality Sensors by Keynes Controls
The ARGES range of intelligent, high performance submersible chemical sensors 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 can be supplied pre-calibrated as stand-alone sensors, or installed in multiparameter systems for immediate deployment.
The multiparameter systems can be configured for real-time measurements or for stand-alone data recording operations.
ARGES Chemical Sensors
Product Features
- Built in SDI12 / RS485 / MODBUS Digital Communications

- Free Windows QLOG Applications Software
Keynes Controls manufacture a range of multiparameter sensor housings that can operate any combination of fluorometer and selective ion sensors. Keynes Controls can supply systems pre-assembled and tested to detect Sewage in waterways.
Options for
- Real-time Measurements
- Stand-alone recording.
- Optional USB Interface
- Free Windows Applications Software
- Optional Submersible Brush unit
An optional water height sensor can be fitted into the multiparameter housing in order to record a profile of the water level above the sensors.
Stand-alone Sensors
A complete range of submersible stand-alone sensors are available for water quality measurements. All the sensors are fully supported in the free Windows applications software and will work directly with many different SCADA applications software.
The sensors can be connected to a local area network, or Wi-Fi using any of the many 3rd party interfaces that are available. Measurement integrity is important in any application. All of the sensors have built-in calibration details that moves around with sensor as they redeployed. The latest calibration date and the name of operator can be stored into the sensors.
Application Software
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.
