|---|---|---|---|---|---|
| 1805 | 2015-05-04 | Loaned | Returned | Lab none | Returned by Pawel Misztal who said it work well for his microbial cultures. |
| 1732 | 2015-02-27 | Lab none | Loaned | Loaned | Loaned to Pawel Misztal in Allen Goldstein's lab for three weeks. Power/data connector, cleaning kit, null modem and tube fittings included. |
| 1731 | 2015-02-27 | Lab none | Calibration | Lab none | Calibrated with zero air and 421.22ppm CO2 God bottle. Zero offset = 53.2ppm, span offset 0.4ppm |
| 1733 | 2015-02-11 | Lab none | Maintenance | Lab none | Installed the cell from the LI-820. This cell might have a bad spot on its wall, but it seemed to clean up okay and was giving stable readings. |
| 1017 | 2013-05-08 | Tonzi | Removed | Lab none | This Li800 was removed from the CO2 profile system on the Tonzi Tower where is was often drifting out of range and railing. |
| 493 | 2012-01-03 | Lab none | Tested | Lab none | Failed in the field with signal pegged at max. In the lab, I confirmed the failure, cleaned the cell, confirmed the source was bright and flashing. Still pegged at max, ran zero air and zeroed but could not span with 436ppm CO2 (error box displayed "Span failed"). No resonable response to differnet cal gases. Reset from configure dialog box with no improvement. Got RMA from Licor. |
| 492 | 2011-12-18 | Tonzi | Removed | Lab none | Removed from the co2 profile system on the Tonzi Tower because it reading was pegged at max (1000ppm). TC wires cut. |
| 426 | 2011-10-17 | Lab none | Maintenance | Lab none | I cleaned the bench. There was one black spec inside the bench and another on the source end. After cleaning, I was able to calibrate the IRGA.
Press = 1003mBar, Temp = 52.6C, Heater = ON, Filter = 0sec, span = 1000ppm. Several cycles of zero air and span CO2 410.49 seemed to bring it back into range. |
| 425 | 2011-10-13 | Tonzi | Removed | Lab none | Removed from the CO2 profiles system because of strange values and would not calibrate. |
