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.
