EMS_6 Series and EXO Water Quality Sondes

EXO1 Multiparameter Sonde


The EXO advanced water quality monitoring platform includes the versatile multiparameter EXO1 sonde for estuarine, surface water, or ground water applications.


Key Benefits
• High-accuracy sensors with on-board memory
• Wireless communications
• Fast response times for profiling and sampling
• 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

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

Sample 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
