Specification sheet for the Sensaphone Web600 — a standalone, web-based remote environmental monitoring system for temperature, humidity, air quality, and water leak detection.
Specification sheet for the Sensaphone Web600 — a standalone, web-based remote environmental monitoring system for temperature, humidity, air quality, water leaks, and other critical conditions.
The Web600 provides flexible web-based remote monitoring at an affordable price. It tracks critical temperatures and other conditions and notifies users immediately when values exceed the normal range. Commonly used for cold food storage, medical cold storage, computer rooms, and data centers. Connect up to six external sensors — each input zone accepts a temperature sensor, an analog transducer, or a dry contact switch. A built-in web server provides live status, quick configuration, and time-stamped history reports available online. When conditions exceed normal values, the Web600 sends e-mail and text message alarm notifications to up to eight contacts. An optional battery backup module (FGD-W610-B) allows monitoring of power failures and keeps the unit operational for two full hours during an outage.
