Environmental Monitoring
Environmental monitoring solutions are designed to protect the worlds most precious resource 'Water' !!
Our instruments are modular measurement tools created to meet a large variety of applications to collect baseline
measurements and deliver a deeper understanding of trends that can be used for fast event detection and response.
ARGES water quality sensors can be connected to any data gathering systems, generating reliable and accurate data and communicating on the common SDI12, RS485 sensor bus or using Modbus protocol. Modular in nature, they allow users to assemble a monitoring package that fits individual site requirements. The state-of-the-art power management
enables systems even in the most remote locations to be deployed.
ARGES Chemical Sensors

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 Intelligent Water Quality Sensors by Keynes Controls 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.
