Go more places with the EXO2s sonde!

The more maneuverable monitoring platform.

EXO2s is a compact, 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 lightweight is optimal

What's in the Box:

• EXO2s Sonde
• Probe Guard
• Calibration and Storage Cup
• Removable Bail
• USB Drive (contains Kor Software)
• Maintenance Kit (port plugs, o-rings, lubricant)

Key Benefits

• Highest Data Quality | Onboard monitoring systems verify sensor operation
• Multiparameter Monitoring | 7 universal ports allow for any combination of smart sensors or the central wiper
• Industry-leading Anti-fouling | Best-in-class wiper technology
• Titanium Components | The toughest grade parts guarantee operation well into the future
• Seamless Integration | EXO can plug and play into marine, estuarine, freshwater, and groundwater monitoring systems

Discover how less size can bring more value to your science with the following benefits:

• Take off the strain, with a 30% reduction in weight.
• Go new places, with a 33% reduction in length.​
• Explore your environment, with AUV's or drones.
• Expand your integrated system, and maximize your limited space.
• Lose the Alkalines, and save on maintenance.
