Calibration method:
Follow the calibration procedure on page 199 of the manual (Operation Manual Model T200, Nitrogen Oxide Analyzer), . An 889.5 ppb (+ or - 5%) NO gas is used to calibrate, . In 6 months, the drift was ~50%
Calibration drift estimate:
Low (on the order of weeks)
Calibration schedule:
As Needed
Uncertainty estimation method:
N/A
Known interferences:
CH3ONO, organic nitrates, nitric acid, and other NOy compounds are all measured as NO2

Additional notes:
Since the lines are dark, the NOx may react in the lines
Measurement uncertainty:
+/- 10%
Measurement units:
PPM
