Title: Calibration
Notes: Trueppm = Probeppm*1.019 + -108.4; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 383ppm, 597ppm, and 2238ppm. Ta=21.8C, P=102.3kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Jaclyn.
