| Four standard gases are measured for 15 min each, and then sample air is measured for about 2 hours. Since we obtain both standard gases series data before and after the sample air measurement, CO2 concentration for sample air is caluculated from virtual standard measurements at that time estimated from their drifts during 2 hours. | |
| Every 1sec data producd by NDIR is recieived by PC and averaged every 5 sec. One minute data is created from the five second averaged data every minute and stored with the gas selections data (satandards 1, 2, 3, 4 and sample) in the hard drive in PC and the server connected via internet at the site. The PC tempolarly calculate CO2 concentration using standard gas calibration curve created before the sample air measurement. | |
|
[Hourly] Hourly data are taken from the arithmetic mean of observed data for one hour after the irregular and evident error data are rejected. ( i.e; 13:00 data is avereged the date from 13:00 to 13:59) [Daily] Daily mean concentrations are calculated by averaging the hourly data obtained during the reported day. [Monthly] Monthly mean concentrations are calculated by averaging the daily data obtained during the reported month. |

| Stndarad gases are used for over one year. CO2 concentration of these standards are measured again after the usage and stability and drift of the assigned values are checked. Therefore, final CO2 caluculation is obtained after the recalibration of standard gases. | |
