T6640 WebSensor with PoE - Remote Temperature, Humidity, CO2 Concentration with Ethernet Interface

Temperature, humidity, and carbon dioxide sensor with Power over Ethernet. Remote alarm.

Web-based sensor with integrated temperature, humidity, and CO2 sensor with PoE function.

A multi-point CO2 and temperature adjustment procedure provides excellent CO2 measurement accuracy across the entire working temperature range; this is 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, requires no maintenance, and offers excellent long-term stability.

The CO2 concentration is displayed on the screen or indicated by a colored LED. Processing and analysis of measured data:
Online in COMET Cloud
COMET database software
Integration into third-party systems

Measuring range extension possible at an additional cost:
Measuring range: 0 to 10,000 ppm
Accuracy: 100 ppm + 5% of the measured value at 25°C and 1013 hPa
