T5540 – WebSensor – Remote Monitoring CO2 Concentration With Ethernet Interface
A multiple point CO2 and temperature adjustment procedure leads to excellent CO2measurement 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
