World class multiparameter water quality testing probes now include built in data logging capabilities
Jul 08 2020
The new AquaSonde range from Aquaread brings built in data logging capabilities to their range of reliable multiparameter water quality testing probes. The AquaSondes are powered by internal lithium batteries to extend the duration of deployments for as long as 180 days, model and logging rate dependent. All AquaSondes feature an internal memory that is capable of storing up to 150,000 full data sets, that equates to over 3 years continuous data logging.
These logging devices can be deployed on their own for a discrete deployment or they can be deployed with a vented cable allowing for barometric compensation of measurements, specifically depth and % saturation of dissolved oxygen. Each AquaSonde is supplied with a QuickDeploy Key, used to initiate the probe’s logging regime and SondeLink PC software for complete logger set up, sensor calibration and data collection.
The Aquasonds feature programmable logging, event and cleaning rates. The fastest logging rate is 0.5Hz and slowest logging rate is 120 hours. Event testing and logging is possible on any single parameter programmable between 1 minute and 99 hours. Programmable cleaning rate is available when using the AP-7000 with its built in self cleaning system.
SondeLink is the free PC application used with all Aquasonds to provide live data viewing, live data logging directly to PC, full calibration and report generation, retrieval of logged data, logged data output to spreadsheet and text files, full set-up utility and site name and GPS geotagging via an integrated USB interface.
Each AquaSonde is supplied with a quick deploy key. When fitted to the AquaSonde, this unique device seals the connector, automatically starts the pre-programmed logging regime and provides instant visual indication of AquaSonde health, battery and memory condition.
This allows all programming of the AquaSonde to be performed at your office using the PC application and the logging regime to be started at the precise time of deployment. It also provides peace of mind that the AquaSonde is operating correctly at the time of deployment.
All models feature an internal barometric pressure sensor that is used when calculating depth and percentage saturation of dissolved oxygen (DO). If the AquaSonde is to be deployed for more than a day at a time and accurate depth and % DO values are required, a vented cable is recommended. For profiling, dip testing or short-term deployment during which time the change in barometric pressure will be negligible, a vented cable is not necessary.
If a vented cable is to be used with the Aquasond then a special data hub is required. This option is a termination device for the vented cable that allows a desiccant bottle to be attached and provides a USB port for data retrieval and a visual indication of AquaSonde health, battery and memory condition.
By attaching a PC running SondeLink to the USB port, direct access can be gained to the AquaSonde allowing live data viewing, live data logging directly to PC, retrieval of logged data and full setup, all whilst the AquaSonde is submerged.
Finally there will soon be options for Bluetooth connectivity for use with mobile apps. Embedded site data and GPS geotagging via the app.
