CO2

CO2 measurements range from parts-per-million to percentage levels. Percentage-level readings occur within closed processes such as fermentation and controlled-atmosphere storage, and in life-science applications like CO2 incubation, where CO2 replaces oxygen and can pose a health risk at elevated concentrations.

Technology

What makes Vaisala's CARBOCAP® technology unique

Vaisala GMP80 CO2 probe with handheld indicator

Vaisala uses single-beam, dual-wavelength NDIR (non-dispersive infrared) technology, with a tunable band-pass filter that Vaisala designs and manufactures in-house in its own cleanroom. The CARBOCAP® design captures the CO2 absorption signal and a genuine reference signal using the same set of components in every measurement cycle, eliminating the drift typical of other NDIR sensors.

Exceptional long-term stability and extended service life
Operation in demanding environments — heat, humidity, dust
Calibration intervals of up to 5 years
Light source rated for 15+ years
Immediate accurate readings, with no environmental adaptation phase
Suitable for 24/7 occupied spaces and industrial settings
