Portable Handheld Multigas Monitors with Carbon dioxide CO2

In some cases not only will you need to detect the common confined space gases (H2S, CO, O2, & LEL) you may also need to detect for CO2 with a NDIR sensor. If that is the case, some multigas monitors allow up to 6 different sensor combinations.

NDIR (Nondispersive Infared) sensors are used to measure Carbon dioxide CO2 concentrations in either ppm (parts per million) or % by volume. As gas enters into the NDIR sensor, the electronics measure the absorption of the characteristic wavelength of light. NDIR CO2 sensors are used mostly for dissolved Carbon dioxide for applications such as beverage carbonation, pharmaceutical fermentation and CO2 sequestration applications.

Depending on your specific application or needs, you can choose the appropriate gas detector and sensor combinations. If you are in need of help, please do not hesitate to contact us for assistance or guidance in choosing the proper gas detector.

Carbon Dioxide Information


NDIR CO2 sensors are also used for dissolved CO2 for applications such as beverage carbonation, pharmaceutical fermentation and CO2 sequestration applications.

Carbon Dioxide or CO2 is typically detected by use of a NDIR (Nondispersive Infrared) sensor in the ppm range.


Carbon dioxide is one of the most frequently overlooked of all toxic gases. Even to refer to CO2 as a toxic gas is a surprise to many safety professionals. In Germany and Austria, regulations already require direct measurement of CO2 during most confined space entry procedures.


Typical uses for IR CO2 sensor is; Indoor Air Quality, Beverage & Brewery, Food Industry, Hospitals, Respirable Breathing Air Testing, Pharmaceutical Fermentation, Winery, Industrial Hygiene Services & CO2 Sequestration applications.


Depending on your specific application or needs, you can choose the appropriate gas detector and sensor combinations. If you are in need of help, please do not hesitate to contact us for assistance or guidance in choosing the proper gas detector.
