T6640 | Temperature Humidity CO₂ Sensor with PoE

Temperature, humidity, carbon dioxide t-line Web sensor with Power over Ethernet feature. Remote alarm.

Web Sensor with built-in temperature, humidity, CO₂ sensor with PoE function.

A multiple point CO₂ and temperature adjustment procedure leads to excellent CO₂ measurement accuracy over the entire temperature working range; this is a must for process control and outdoor applications. The dual wavelength NDIR CO₂ sensing procedure compensates automatically for ageing effects. The CO₂ module is highly resistant to pollution and offers maintenance free operation and outstanding long term stability.
