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.
Construction
ARGES Fluorometers
The ARGES Fluorometer are manufactured from high quality stainless steel tube with coated optics. The network connector is rates to 2 km and can be wet mated if required and has gold plated pins to prevent corrosion.

Calibration Period
The advanced design of Intelligent submersible chemical sensors means that the time between re-calibration of instrument is minimised. Keynes Controls recommends a check calibration every 12 months. A User can adjust the submersible fluorometer sensor calibration for a specified range to improve accuracy for dedicated tasks using the calibrations solutions manufactured by Keynes Controls and are available from the online shop.
The image shows a multi-parameter system being prepared for use. Each of the sensors are separately calibrated. The single-ion and fluorometers can be combined into a single instrument for dedicated tasks.
Optional Extras
Any combination of the ARGES sensors can be installed into 3-Sensor and 7-Sensor Multi-parmameter housings and connected to a data acquisition system via the gold plated wet-mate subsea connector mounted on the top of the housing.
Eye-bolts can be screwed into the top of the SONDE in order to fasten a strain-relief cable that can be used to secure the sensor housing into position on deployment.
The Multi-parameter housings can be configured with any range of sensor in order to create flexible monitoring solutions.
All of the sensors can be used stand-alone, distributed across a network and integrated with other similar sensors from 3rd party suppliers

Communication Options
All of the Keynes Controls ARGES chemical sensor range support SDI12, RS485 and MODBUS digital communications. The submersible fluorometers all have the option to have an analogue output in the range of 0 - 2 V DC proportional to the measured concentration.
Accessories
Keynes Controls manufactures a range of accessories that can be used to connect the ARGES range of sensors to a Windows Computer system system and enable the sensors to be used in Laboratory applicaion, multiple -parameter instruments and calibration operations.
The option USB media converters can be used to connect a multi-paramter instrument to a a PC.
A virtual communications port feature is available enabling the software to talk to the instrument across a Local Area Network of Wi- Fi Connection.
The ARGES Fluorometer range, seamlessly integrates into the powerful Q-LOG software.
Our Q-LOG software runs on the widely recognized Windows Operating system, you have the ability to calibrate, adjust instrument network address, and effortlessly display measurements on a series of panel meters and charts. Conveniently store results in text based files for quick analysis in spreadsheets.
Our highly accurate fluorometers provide chemical concentration and local temperature readings in SI units (Engineering units). Customize the SI units based on your instrument's capabilities, including support for multiple units like turbidity sensors, all easily managed through the device setup.
Experience the convenience of Q-LOG, enabling you to effortlessly make and install calibration values into your instrument.
Connect our Fluorometers directly to SDI12, RS485, and MODBUS networks, leveraging the versatility of Q-LOG to acquire measurements on SDI12 and RS485 networks. SDI12 communications are perfectly suited for seamless integration with data loggers, while RS485 is ideal for larger-scale network applications. Maximize efficiency by simultaneously testing all sensors of a multi-parameter instrument prior to deployment.
For added convenience, the optional USB interface allows you to comprehensively test and validate the sensors' operations, ensuring seamless integration into your own application. Trust in the performance and accuracy of our multi-parameter systems!
