NOTE: This sensor must be installed into an EXO Sonde to function. Does not function on its own.

  • 0 to 50 mg/L measurement range
  • T63<5 sec response time
  • ±0.1 mg/L or 1% of reading accuracy from 0 to 20 mg/L

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.
