T6641 WebSensor with PoE - Remote Temperature, Humidity, CO2 Concentration with Ethernet Interface

Temperature, humidity, and carbon dioxide web sensor with Power over Ethernet (PoE). Remote alarm.

Web sensor with temperature, humidity, and CO2 cable probes with PoE functionality.

A multi-point CO2 and temperature adjustment procedure provides excellent CO2 measurement accuracy across the entire operating temperature range, essential for process control and outdoor applications. The dual-wavelength NDIR CO2 detection procedure automatically compensates for the effects of aging. The CO2 module is highly resistant to contamination, offers maintenance-free operation, and excellent long-term stability.

The device is supplied with probes with 1 m cables. Cable lengths of 2, 4, and 10 meters are optionally available. Processing and analysis of measured data:
