| 1421 | 2013-01-08 | Lab none | Calibration | Lab none | Trueppm = Probeppm*0.9955 + -27.3; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 421ppm, 3056ppm, and 10000ppm. Ta=22.3C, P=102.5kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied.
