Comet WebSensor - remote CO2 concentration with Ethernet interface

CO2 - carbon dioxide t-line Web sensor. Remote alarm.

Web Sensor with built-in concentration CO2 sensor.

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.

The CO2 concentration is shown on the display or signaled by a color LED.
