IRC-AT Carbon Dioxide - 2

IRC-A Perf C-AT erformance Data IRC-AT Performance Data Figure 2 Beer Lambert Performance 0.16 Typical response from 0 to 5000ppm CO2. The fit is very close to the theoretical curve, predicted by the Beer-Lambert Law. 0.12 0.10 0.08 0.06 Model fit using standardised coefficients Custom linearisation is not necessary with the IRC-AT. Using universal linearisation constants, repeatability between cells is very good, allowing easy implementation. For an IAQ application, a zero and then single calibration at 4000ppm CO2 gives the error shown above: typically less than ± 40ppm from 0 to 4500ppm....
