G2-UW Environmental Monitor

The NexSens G2-UW provides live data access to many compatible sensors. Included solar power pack and integral cellular system provide real-time data and notifications.


Simple Integration with Sensors

Connect a sensor to the G2-UW's UW plug connector and let the system autodetect the pre-configured parameter output and begin recording. No need to manually configure the logger to record the correct data.

Real-Time Updates

An embedded cellular modem provides live, customizable weather and water quality notifications on a mobile device or computer.

Fully Featured Design

The G2-UW incorporates logger, transmitter, solar power, and online data management into a streamlined design. All equipment comes pre-mounted to a 2" NPT MAST. This simplifies setup and maintenance and allows the system to be used in a wide range of applications and environments. A customer simply needs to connect their sensor and the G2-UW begins recording and transmitting data.
