Comet CO2 Concentration Thermometer Hygrometer with RS485 interface, duct mount

Comet CO2 concentration transmitter with 0-10V output, built-in carbon dioxide sensor

Duct mount CO2 concentration t-line WebSensor.

Transmitter with built-in concentration CO2, temperature, relative humidity sensor for duct mount.

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
