YSI EXO Conductivity & Temperature Smart Sensor

Note: This product is intended for sampling and profiling applications.
This sensor must be installed into an EXO Sonde to function (EXO1 | EXO2). Does not function on its own.

For long-term monitoring in fouling environments, please see our Wiped (C/T) sensor for the EXO2 platform.

The EXO conductivity & temperature sensor is a digital smart sensor featuring welded titanium construction and wet-mateable connectors. A new metrology system specifically for EXO offers improved range of conductivity and increased accuracy of temperature sensors to better address oceanographic challenges.

  • 0 to 200 mS/cm measurement range
  • T63<2 sec response time
  • ±0.5% of reading or 0.001 mS/cm accuracy from 0 to 100

Compact and Accurate

The EXO platform offers a completely new approach - highly accurate, quick-response sensors in a small, easy-to-deploy and easy-to-maintain package. Gone are large and complicated sensor arrangements requiring complex integration.

Smart Probes

All EXO sensors have onboard memory and processing, allowing users to easily calibrate and configure sensors at one location and distribute to various field sites.

Smart Ports

Wet-mateable connectors allow for swaps in wet conditions, while the smart ports shut down any excessive current draws to prevent damage.
