thick film gas sensors Non-Dispersive Infrared or sensors (NDIR) to measure the CO2 concentration (Miyachi et al. 2003). Even though the thick film type is more affordable than the NDIR gas sensor, the latter type has more technological advantages such as long term stability and high accuracy (Park et al. 2010). On the other hand, some
devices were not available for utilization in NDIR gas sensors until the late 1950’s. • The first ever NDIR gas sensor for sale was the Beckman LB-I medical CO 2 analyzer in the early 1960’s for measuring end-tidal CO 2 levels for cardiac patients in hospital ICUs. • The Beckman LB-I was single-beam designed having a DC-operated infrared source chopped at 40 Hz by a small mechanical ...
Most of our CO2 products use non-dispersive infrared (NDIR) carbon dioxide sensors. These rely on an infrared light source and detector to measure the number of CO2 molecules in the sample gas between them. Over many years, both the light source and the detector deteriorate, resulting in slightly lower CO2 molecule counts. The industry calls this "drift". To combat sensor drift, during ...
