| Rec No. | Date | Loc From | Title | Loc To | Notes |
|---|---|---|---|---|---|
| 1186 | 2014-01-24 | Tonzi CO2 Probe Tree2 Profile -0.08 | Removed | Lab none | Removed from Tonzi tree #2 at -8cm for lab calibration |
| 1138 | 2012-03-02 | Lab none | Installed | Tonzi CO2 Probe Tree2 Profile -0.08 | Installed at Tonzi in the Tree2 set at -8cm |
| 1416 | 2012-02-15 | Lab none | Calibration | Lab none | Trueppm = Probeppm*1.098 + -121.7; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 436ppm, 2238ppm, and 10000ppm (N2 bal). Ta=26.7C, P=101.9kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Siyan. |
| 1364 | 2010-03-01 | Lab none | Calibration | Lab none | Trueppm = Probeppm*1.121 + 35.69; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 383ppm, 597ppm, and 2238ppm. Ta=20.2C, P=101.9kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Jaclyn. |
