Vaisala CARBOCAP® Sensor for measuring carbon dioxide

The CARBOCAP® story began in 1992, when micromechanical sensors were being intensively researched at Vaisala. The groundbreaking idea of miniaturizing the Fabry-Perot Interferometer (FPI) was born, leading to collaborative development work with VTT Technical Research Center of Finland.

Later, a patent application was submitted for a single-channel gas concentration measurement method using the FPI. The driving force behind the innovation of the CARBOCAP® sensor was Vaisala's commitment to developing superior technologies for environmental measurements. And indeed, Vaisala’s pioneering work in the field of silicon-based NDIR technology and electrically tunable filters resulted in the compact, simple and high-performance CARBOCAP® sensor. To this day, the long-term stability and reliability of the measurement provided by the FPI is unrivaled.

The first commercial CARBOCAP® products for measuring ppm-level CO2 in ventilation applications were launched in 1997, with instruments for percentage-level CO2 measurements following soon after. CARBOCAP® technology is proven in a wide range of applications, including ecological measurements, where it performs reliably in harsh environments such as soil and snow, satisfying the thirst for knowledge that scientists have for understanding nature´s processes. see how the technology works! Or watch video about the CARBOCAP® Technology.
