GRI H8800R Humidity Sensor with Remote Probe

Protect critical infrastructure with the George Risk Industries H8800R humidity sensor — a cost-effective solution for continuous environmental monitoring in data centers, server rooms, labs, and storage facilities. This humidity sensor supports a remote probe up to 500' so you can place the sensing element exactly where moisture risk is highest, while the main unit stays in a secure location. The H8800R operates on low-voltage power (nominal 15 VDC, 7.5–15 VDC range) and features non-volatile memory to preserve calibration and alarm settings during power interruptions. Its wide temperature capability (-40°F to 185°F with the probe; -10°F to 176°F without) ensures dependable performance in extreme conditions. Designed for easy, hybrid installation and wired integration, the H8800R is compatible with Sensaphone dialers and other security/monitoring systems, enabling fast alerts and automated responses. Ideal for surveillance-supporting environmental controls, preventive maintenance, and compliance monitoring. Add the H8800R to your monitoring strategy to reduce downtime, protect assets, and enhance facility security — contact us to integrate it into your system or place an order today.
