G2-RAIN Alert System

The NexSens G2-RAIN Alert System incorporates a precision tipping bucket rain gauge with cellular data communication and real-time notifications


Real-Time Updates

An embedded cellular modem provides live, customizable rainfall notifications on a mobile device or computer.

Streamline Design

Integrated mount and up to 4 year battery life make setup and deployment easy. Simply screw the G2-RAIN onto a 2” NPT threaded MAST.

Integrated Syphon with Debris Filter

Syphoned rain gauges provide more accurate measurements by regulating the water flow for rainfall rates up to 27” (700mm) per hour. A built in filter prevents debris from clogging the entry.

WQData LIVE Web Data Portal
