Calibration |
| Notes: |
Last calibration: 2012-07-12
Cell Pressure=127.70Torr, Cell Temperature=22.53C, Ring Time=11.885usec
God Bottle at 300psi
CH4 Span=1.8978ppm
CH4 = 1.830 -> 1.897 Offset: 67.8ppb
Notes: This analyzer was removed from the field yesterday for low pressure problems. Pressure seems better but fell from 142Torr on start up. The calibration was used to check a secondary cal tank. About 70 readings gave an average of 3.905ppm CH4
