Calibration |
Lab none |
Trueppm = Probeppm*1.004 + 19.27; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 3056ppm, and 10000ppm. Ta=22.7C, P=102.1kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Patty. |
