Smart Sondes and Sensors
EXO is an extremely versatile instrument, allowing the user to automatically configure a sonde with different sensors for different applications in minutes

Smart Sensor Options:
• Conductivity/Temperature (wiped and non-wiped)
• Dissolved Oxygen
• fDOM
• ISEs (AmmoniumChloride, and Nitrate)
• pH (guarded and unguarded)
• pH & ORP (guarded and unguarded)
• Rhodamine
• Total Algae (Chlorophyll + Phycocyanin and Phycoerythrin)
• Turbidity

Other Available Parameters
• Absolute Pressure
• Ammonia
• Depth
• DO% Local
• Guage Pressure
• nLF Conductivity
• PAR
• Resistivity
• Salinity
• Specific Conductivity
• Total Dissolved Solids
• Total Suspended Solids
• Water Density

Accuracy
EXO sondes and sensors are 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 smart sensor 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 anti-fouling systems protect data integrity
• Low power consumption extends underwater deployments

Other EXO Sonde Options
• EXO2 Sonde offers the same features as the EXO2S, but includes battery compartment
• EXO1 Sonde (4 ports) — also available without battery compartment
• EXO3 Sonde (5 ports including Central Wiper port) — also available without battery compartment
