GRI 2808 Absence Of Water Sensor, Self Powered/2.5 Minute Sample Rate, Form Relay Output

Protect critical assets with the George Risk Industries GRI 2808 Absence of Water Sensor — a submersible, self-contained liquid leak sensor built for dependable, low-maintenance monitoring. Designed for security, facility monitoring and infrastructure surveillance, the GRI 2808 reports both the presence and absence of water, helping prevent equipment damage, downtime and costly recovery. The microprocessor samples once every 2.5 minutes (custom rates available) and the unit is powered by a 5-year lithium battery while also supporting 12V DC/hybrid installations for flexible deployments. A Form C relay output lets you trigger wired alarm panels, wireless transmitters or BMS/SCADA systems for immediate notification and automated response. With wired connectivity and a rugged 12" cable, the sensor is built to perform in server rooms, pump stations, basements, data centers and other high-value areas where reliable leak detection and security monitoring matter. Backed by George Risk Industries engineering and a 1-year limited warranty, the GRI 2808 simplifies integration into existing surveillance and monitoring systems.
