2037 2015-11-03 Tonzi CO2 Probe Tree1 Profile -0.02 Removed Lab none Removed from the Tonzi Tree 1 profile at -2cm due to bad readings. Replaced by sn L2010069
2073 2014-12-09 Tonzi CO2 Probe Tree1 Profile -0.02 Location Tonzi CO2 Probe Tree1 Profile -0.02 Tonzi Tree1 profile at -2cm
2023 2014-03-18 Tonzi CO2 Probe Tree1 Profile -0.04 Moved Tonzi CO2 Probe Tree1 Profile -0.02 At Tonzi in the Tree 1 profile this probe was moved from the -4cm location to -2cm
1994 2014-01-29 Lab none Installed Tonzi CO2 Probe Tree1 Profile -0.04 Installed at Tonzi in the Tree 1 profile at -4cm with new U-shaped tops on the PVC enclosures
1435 2014-01-27 Lab none Calibration Lab none Trueppm = Probeppm*1.287 + 388; 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.
1179 2014-01-24 Tonzi CO2 Probe Tree1 Profile -0.04 Removed Lab none Removed from Tonzi tree #1 at -4cm for lab calibration
1131 2012-02-16 Lab none Installed Tonzi CO2 Probe Tree1 Profile -0.04 Installed at Tonzi in the Tree1 set at -4cm
1406 2012-02-06 Lab none Calibration Lab none Trueppm = Probeppm*1.063 + -34.27; 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=24.2C, P=101.5kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Siyan.
1369 2010-03-02 Lab none Calibration Lab none Trueppm = Probeppm*1.078 + -11.78; 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=22.2C, P=101.5kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Jaclyn.
4636 2010-01-08 Tonzi CO2 Probe Open Profile -0.04 Location Tonzi CO2 Probe Open Profile -0.04 Pulled out for ambient air reading and put back.
4546 2008-03-06 Lab none Installed Tonzi CO2 Probe Tree1 Profile -0.04 Installed in the Wast under tree profile at -4cm. mV and ppm readings in air were recorded before installation.
