Description

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.

Green LED shines - CO₂ concentration 0 to 1000 ppm
Yellow LED shines - CO₂ concentration 1001 to 1200 ppm
Red LED shines - CO₂ concentration 1201 ppm and more
