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:
