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. EXO2s 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
Key Benefits
• High-accuracy sensors with on-board memory
• Wireless communications
• Seamless integration into marine, estuarine, freshwater and ground water monitoring systems
Smart Sondes and Sensors
Extremely versatile instrument, allowing the user to automatically configure a sonde with different sensor for different applications in minutes
Accuracy
Tested in a variety of rigorous field conditions as well as lab conditions to ensure accuracy and response times
Monitor without Interruption
No matter which EXO sensors users select, other features of the sensors' design make them rugged and durable:
• Wet-mateable connectors resist corrosion
• Isolated components prevent short circuits
• Welded housings and double o-rings prevent leaks
• High-impact plastic and titanium resists breaking
• Built-in antifouling systems protect data integrity
• Low power consumption extends underwater deployments
