GMM111 Carbon Dioxide Module
The Vaisala CARBOCAP® Carbon Dioxide Module GMM111 is a CO2 measurement module with flow-through aspiration.
Features/Benefits
GMM111
The Vaisala CARBOCAP® Carbon Dioxide Module GMM111 is designed especially for control of biological processes where high CO2 concentrations are used. It has 3 optional measurement ranges 0 . . . [. . . ] 20 % CO2 Excellent long-term stability
CARBOCAP® sensors results largely from the stable reference provided by the electrically tunable Fabry-Perot Interferometer(FPI). The tunable FPI filter measures CO2 absorption, and simultaneously a reference wavelength. This internal reference measurement compensates effectively for any changes in the optical path, such as light source intensity changes and contamination. In the HVAC market, this type of reference measurement is a unique feature to Vaisala CARBOCAP® products. The true internal reference measurement of Vaisala CARBOCAP® CO2 transmitters provides years of stable CO2 measurements.
