Last calibration: 2010-01-14
Cell Pressure=138.16Torr, Cell Temperature=20.17C, Ring Time=13.987usec
God CH4 at psi CH4 Span=1.8978ppm, CO2 Span=382.50ppm
CH4 = 1.834 -> 1.903 Offset: 0.064ppm
CO2 = 354 -> 383 Offset: 28.5ppm
Notes: Testing with CH4 standard 4.978ppm CH4 and 3ppm CO2 LGR reading: 4.785ppm +- 9ppb CH4 CO2 reading -1.00 Maybe out of range Testing with CO2 standard 597.4ppm CO2 ??ppm CH4 LGR reading: 2.701ppm +- 9ppb CH4 LGR reading: 582ppm +-4ppm CO2 This analyzer seems noisier than the single channel. Will check other FGGA analyzer after swap. |
