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

Monitoring Made Mobile
EXO makes it easy to view data in the field. The EXO Handheld offers a dedicated, streamlined interface to EXO sondes. EXO GO uses Bluetooth to connect any Windows OS device to a submerged EXO sonde.

Other EXO Sonde Options
• EXO1 sonde has 4 ports and a smaller diameter
• 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
