The SST GIR910 Infrared Carbon Dioxide Gas Sensor is a completely self-contained device that measures and displays the concentration of carbon dioxide accumulated in a protected area and transmits this information to a central point. The SST GIR910 uses the proven non-dispersive infrared (NDIR) principle to detect and monitor the presence of CO2.
Using an infrared source lamp and an optical Sensor with a narrow-band filter, an analysis of the optical absorption through the gas allows the concentration of the target gas to be determined. A second infrared sensor operating at a wavelength not affected by the target gas is used to eliminate effects resulting from ambient and physical variations. These include temperature changes, source and filter degradation and particle scattering.
