The EXO guarded Nitrate ISE (ion-selective electrode) 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.

Note: Intended for sampling applications. Not for use in an EXO system with a central wiper installed.

• Measures NO3 in freshwater applications
• Depths not to exceed 17 meters (55 ft) or 25 psi
• 3 month warranty on sensing module

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
• EXO 1 Sonde has 4 ports and a smaller diameter
• EXO 2 Sonde has 7 ports for the ultimate monitoring platform
• EXO 3 Sonde has 5 ports for a lower cost option using the central wiper
• EXO 2s Sonde offers the same features as the EXO2, but without the battery compartment
