EXO3 Multiparameter Sonde

5-Port Multiparameter Water Quality Sonde

The parameters you need, without the features you don't!

Offering the greatest value of any sonde available on the market, EXO3 combines the maneuverability of the EXO1 with the powerful antifouling wiper of the EXO2.


EXO3 is a purpose-built sonde for monitoring major water quality parameters, including: pH, conductivity, temperature, turbidity, and dissolved oxygen.

Key Benefits
• High-accuracy sensors with on-board memory
• Wireless communications
• Seamless integration into marine, estuarine, freshwater and ground water monitoring systems

Smart Sondes and Sensors
Extremely versatile instrument, allowing the user to automatically configure a sonde with different sensor for different applications in minutes

Accuracy
Tested in a variety of rigorous field conditions as well as lab conditions to ensure accuracy and response times

Monitor without Interruption
No matter which EXO sensors users select, other features of the sensors' design make them rugged and durable:

• Wet-mateable connectors resist corrosion
• Isolated components prevent short circuits
• Welded housings and double o-rings prevent leaks
• High-impact plastic and titanium resists breaking
• Built-in antifouling systems protect data integrity
• Low power consumption extends underwater deployments
 

But that's just the beginning of the great benefits EXO3 has to offer:

Maintenance Special
The best priced, highest-quality sonde for
baseline water quality monitoring.

 

 YSI Integrated Systems
Flexibility to switch from continuous monitoring to
spot sampling with a lighter, shorter form factor.

 

YSI Integrated Systems
Integral SDI-12 communications makes it ideal for existing data collection 
platforms and installations. (Including replacement of 6-Series sondes.)

 

EXO University
Plug-and-play design with all existing EXO platform smart sensors,
including Total Algae, fDOM, and Wiped Conductivity & Temperature.



EXO University
The best antifouling wiper in the industry, protecting your 
sensors for up to 90 days in the harshest conditions.
