Title: Calibration
Notes: Trueppm = Probeppm*0.9432 + -643; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 436ppm, 2238ppm, and 10000ppm (N2 bal). Ta=26.6C, P=101.6kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Siyan.
