Calibration |
| Notes: |
Last calibration:
Zero Air at 900psi, AMP CA04119 4223.8 ppb CH4 at 850psi
CO2 zero Offset: -20.9ppm
H2O zero Offset: -93.5ppm
CH4 zero Offset: 0.1ppb
CH4 span Offset: 33.7ppb
Notes: First calibration in the lab for sn TG10-01751. Ran zero and span gases at our usual flow rate of 2 SCFH and plumbed the system with the recommended 30cm vent before the air inlet to vent excess air pressure and to prevent diffusion of ambient air into the gas stream. It took more than 45min for H2O zero to stabilize. |
