Compact, batteryless, customizable and best-in-class water quality monitoring instrumentation platform
Xylem's YSI EXO2s is a multiparameter water quality sonde featuring 7 sensor ports (or 6 sensor ports with a central wiper port). An optional depth sensor is also available. The EXO2s offers a 30% reduction in weight compared to the YSI EXO2 thanks to its streamlined design without a battery compartment, providing increased maneuverability and handling.
EXO Multiparameter Sondes are 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.
Cables, probes/sensors, and accessories sold separately.
- High-accuracy sensors with on-board memory
- Onboard monitoring systems verify sensor operation to ensure high data quality
- 7 universal ports allow for any combination of smart sensors for true multiparameter monitoring
- Center sensor port can be equipped with a best-in-class wiper for industry leading anti-fouling capabilities
- Titanium components are the toughest grade parts to guarantee operation well into the future
- Bluetooth wireless communications
- Seamless integration into marine, estuarine, freshwater and ground water monitoring systems
- Light weight which is ideal for horizontal profiling or use with an AUV (Automated Underwater Vehicle) or a drone.
Go more places with the EXO2s sonde!
The more maneuverable monitoring platform.
We have heard from customers who need the payload and capabilities of YSI’s best-in-class EXO2 sonde, but in spaces and places that can’t accommodate the EXO2. YSI EXO2s (shorty) is a customized, batteryless sonde that comes with the same warranty and capabilities as the EXO2, and is ideal for specialized applications such as:
- Attachment to an AUV or aerial drone
- Integration with a buoy
- Horizontal profiling where light weight is optimal
