  • Overview

    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
