Lab none |
Trueppm = Probeppm*1.014 + 23.21; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 406ppm, 2238ppm, and 10000ppm (N2 bal). Ta=26.2C, P=101.4kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Sara. |
