Calibration |
Lab none |
Trueppm = Probeppm*1.746 + -27.77; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 2238ppm, and 3056ppm. Ta=20.19C, P=101.3kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Madeleine. |
