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 ... 5/10/20 % CO2. The GMM11 is a
fl ow-trough model and has barbed
conncectors for attaching the in and
out fl ow tubes. As the module is not
mounted in the chamber, the chamber
can be heatsterilized without
removing the module.
The Vaisala CARBOCAP® CO2
sensors have been proven to be
accurate anddurable. They have an
excellent long-term stability, which
decreases maintenance. The
superior performance of Vaisala |
CARBOCAP® sensors results largely
from the stable reference provided by
the electrically tunable Fabry-Perot
Interferometer(FPI).
The tunable FPI fi lter 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. |
