G2-HYDROMET Weather and Water Quality Monitor

The NexSens G2-HYDROMET is a fully integrated wireless weather and water monitoring station specially configured for use with the YSI EXO3 multi-parameter sonde or the PT-500 vented water level sensor.


Powerful Weather Station

Airmar 110WX compact weather station measures wind, temperature, barometric pressure, and humidity.

Real-Time Updates

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

Optional Hydrological Sensor

Select either YSI EXO3 sonde or an APG PT-500 level sensor for water measurements. The sensor uses a simple thread-in connector to simplify setup and reduce the chance for error.

WQData LIVE Web Data Portal

View live and historic data in a simple and intuitive interface from any web-enabled device. WQData LIVE is optimized for mobile devices to provide a great experience regardless of screen size.

Remote Configuration

No need for a site visit to make configuration changes. Queue the commands online and the remote G2-HYDROMET will be configured on the next transmission connection.
