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.
