Carbon Dioxide

Carbon dioxide (CO2) is a common trace gas in fresh air at higher levels it is useful in hundreds of industries. We offer sensors for measuring CO2 gas levels in both ambient air and at concentrations up to 100%.

Selecting the right product for your application

Ambient air carbon dioxide sensors up to 10,000 ppm are used to measure CO2 levels outdoors or in enclosed areas like offices, classrooms, greenhouses or anywhere precise CO2 levels need to be measured. 

5% to 100% carbon dioxide sensors and products are used around stored CO2 tanks or systems where CO2 leaks can occur. They are also used in enclosed systems like incubators, algae towers or to measure levels where stored CO2 is used to fight fires. Serial RS232, RS485 Modbus, 0-10VDC and 4-20mA outputs available depending on model.

Sensor development kits for all our sensors provide USB connectivity and our free GasLab® software to get you up to speed instantly using or evaluating any of our sensors.
