Calibration |
Lab none |
Trueppm = Probeppm*1.014 + 51.82; 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=25.8C, P=101.9kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Joe. |
