EXO Multiparameter Sondes — the best-in-class platform for the highest quality data. EXO's dynamic range of smart sensors provide comprehensive multiparameter water quality data while SmartQC ensures proper calibrations and top sensor performance. You can be confident in your extended deployments thanks to EXO's tough materials and unmatched anti-fouling technology. The EXO platform includes six sonde options with up to 7 sensor ports (including a central wiper port), optional depth sensor, and battery compartment.
Highest Data Quality - Onboard monitoring systems verify sensor operation
Multiparameter Monitoring - 7 ports allow for any combination of smart sensors or central wiper
Industry-leading Anti-fouling - Best-in-class wiper technology
Titanium Components - The toughest grade parts guarantee operation well into the future
Smart Sensors - Smart sensors store calibrations allowing batch calibration and field sensor swaps
Seamless Integration - EXO can plug and play into marine, estuarine, freshwater, and groundwater monitoring systems
Large memory - Large built in memory for long-term unattended deployments
Accuracy - EXO sondes and sensors are rigorously tested to ensure accuracy and response times. (See resources tab for full list of sensor accuracies)
Optional battery compartment - integrated battery compartments are great for standalone deployment but not needed for self powered telemetry. Removing the compartment reduces the size and cost
Other available parameters: Absolute Pressure, Ammonia, Depth, DO% Local, Gauge Pressure, nLF Conductivity, PAR, Resistivity, Salinity, Specific Conductivity, Total Dissolved Solids, Total Suspended Solids, Water Density
The EXO can be deployed using your computer and the EXOs' built in Bluetooth or using one of the other available communication methods:
| Digital Handheld | Ideal for spot measurement in the field and starting continuous deployments (handheld available with GPS option) |
| EXO GO | Bluetooth device that can be used for communicating with submerged EXOs |
| Telemetry | Remote continuous monitoring that can be used for hassle free deployments letting you know what's happening and |
| Data Buoys | For deployment on lakes and marine applications for monitoring at set depths |
| Profilers | For monitoring parameters throughout the water column |
No matter which EXO sensors you need, the smart sensor design make them rugged and durable:
The versatility of the EXO sonde and extensive range of compatible sensors make the EXO suitable for a wide variety of applications.
