A Test of NDIR-based Sensors for the Near Real-time Analysis of CO₂

摘要: In this study, the reliability of NDIR-based sensors wasexplored by evaluating comparability between measurement systems in near real-time analysis CO₂. For purpose, replicate analyses were performed using two different model types(H-550 and B-530, ELT Company, Korea). Three data each sensor type collected continuously side-by-side three second intervals(a duration 304 hour) evaluated for relative performance NDIR sensors. The reproducibility sensors, when assessed standard error(RSE %) values all units, showed moderate changes with time overall mean 2.33%. When CO₂ measurements from units correlation analysis, results strong comparability, regardless type. study suggest that are reliable enough to produce highly comparable at least a sense.
