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
