EXO Fluorescent Dissolved Organic Matter Digital Smart Sensor

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

  • Overview

    The EXO fDOM (fluorescent dissolved organic matter) Sensor is a digital smart sensor featuring welded titanium construction and wet-mateable connectors. Complete calibration in less than 15 minutes using EXO's suite of smart sensors and intuitive Kor Software.

    Warning: Emits ultraviolet light. Do not look directly into powered optical sensor.

    • 0 to 300 ppb Quinine Sulfate equivalent (QSE) measurement range
    • 0.01 ppb QSE resolution
    • T63<2 sec response time

    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 sensors are auto-recognized from any port of an EXO sonde making sensor payloads interchangeable and completely customizable.

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

    Designed for Use with EXO Multiparameter Sondes
    • EXO1 sonde has 4 ports and a smaller diameter
    EXO2 sonde has 7 ports for the ultimate monitoring platform
    • EXO3 sonde has 5 ports for a lower cost option using the central wiper
    • EXO2s sonde offers the same features as the EXO2, but without the battery compartment
