|---|---|---|---|---|---|
| 5008 | 2020-12-01 | Vaira CO2 probe East Profile -0.08 | Removed | Lab none | The battery bank has died and it has been decided to focus on the forced diffusion soil CO2 and Eosense GP profile. The rest of the soil co2 equipment will be removed. |
| 3127 | 2017-09-21 | Vaira CO2 probe East Profile -0.02 | Moved | Vaira CO2 probe East Profile -0.08 | Moved from East profile at -2cm to East profile at -8cm |
| 3066 | 2017-09-14 | Lab none | Installed | Vaira CO2 probe East Profile -0.02 | Reinstalled at Vaira in the East profile at -2cm after lab calibration. |
| 3027 | 2017-08-25 | Vaira CO2 probe East Profile -0.02 | Removed | Lab none | Removed from Vaira from East profile -2 cm position for calibration. Probe labeled 4. |
| 2174 | 2016-02-23 | Lab none | Installed | Vaira CO2 probe East Profile -0.02 | Installed in the Vaira East profile at -2cm after lab calibration. |
| 2069 | 2014-12-09 | Vaira CO2 probe East Profile -0.08 | Location | Vaira CO2 probe East Profile -0.08 | Vaira East profile at -8cm |
| 1427 | 2014-01-27 | Lab none | Calibration | Lab none | Trueppm = Probeppm*0.9809 + 65.37; 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. |
| 1185 | 2014-01-24 | Tonzi CO2 Probe Tree2 Profile -0.04 | Removed | Lab none | Removed from Tonzi tree #2 at -4cm for lab calibration |
| 1134 | 2012-03-02 | Lab none | Installed | Tonzi CO2 Probe Tree2 Profile -0.04 | Installed at Tonzi in the Tree2 set at -4cm |
| 1415 | 2012-02-15 | Lab none | Calibration | Lab none | Trueppm = Probeppm*1.08 + -56.27; 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. |
| 1409 | 2012-02-06 | Lab none | Calibration | Lab none | Trueppm = Probeppm*0.9987 + 7.368; 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=24.2C, P=101.5kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Siyan. |
| 1375 | 2011-02-01 | Lab none | Calibration | Lab none | Trueppm = Probeppm*1.041 + 3.308; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 383ppm, and 597ppm. Ta=25.5C, P=102.3kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Melanie. |
| 1354 | 2010-02-03 | Lab none | Calibration | Lab none | Trueppm = Probeppm*1.049 + 4.392; 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=24.1C, P=101.2kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Jaclyn. |
| 10 | 2009-12-01 | Factory | Repair | Factory | Vaisala factory repair and calibration 0-1% - certificate on file.
Problem: Got probe error 10 and 11. No IR source Action: Replaced probe circuit board and adjusted unit. |
