Notes: Trueppm = Probeppm*1.027 + 0.2028; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 2238ppm, 3056ppm, and 10000ppm. Ta=25.1C, P=101.5kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Joe.
