GRI H8800 Humidity Sensor

The George Risk Industries H8800 Humidity Sensor is designed for reliable, low-cost environmental monitoring in commercial and industrial security applications. Ideal for server rooms, surveillance equipment closets, museums, cold storage and HVAC systems, the H8800 provides accurate humidity readings with the option to place a remote probe up to 500' away—perfect for locations that are difficult to access.

Built for operations that cannot tolerate downtime, the H8800 features non-volatile memory to retain calibration and user settings during power interruptions. It operates across a wide temperature envelope (no probe: -10°F to 176°F; with probe: -40°F to 185°F) and runs on standard low-voltage DC power (operates from 7.5V to 15V DC, typical input 15V DC), making it easy to integrate with existing security and monitoring infrastructure. Wired connectivity and hybrid installation options streamline setup, and built-in compatibility with Sensaphone dialers lets you add automated alerts for environmental excursions.
