The Power-over-Ethernet (PoE) Duct Temperature Sensor uses an NTC thermistor with 8 ft. lead wires to accurately measure temperatures in duct work, while maintaining a sealed environment. Can be easily installed and mounted for long term use.
The Power-over-Ethernet (PoE) Sensor products measure various conditions (environmental, power, access). All devices come with flexible settings — including notifications, alerts, reports, and maps — can be customized in the iMonnit online sensor management interface.
