LANDFILL GAS MONITORING <br /> GEM 2000 CALIBRATION AND PERTINENT DATA <br /> Date: e fA/fib Site Name: <br /> Technician: Job No. <br /> WEATHER OBSERVATIONS <br /> Wind Speed: /-�- MPH Wind Direction: Barometric Pressure: :;?3,/O"Hg <br /> Air Temperature: 63 OF General Weather Conditions: <br /> CALIBRATION INFORMATION <br /> Pre-monitoring Calibration Precision Check <br /> Procedure: Calibrate the instrument. Make a total of three measurements by alternating zero air <br /> and the calibration gas. Record the readings and calculate the average algebraic difference <br /> between the instrument reading and the calibration gas as a percentage. The calibration <br /> precision must be less than or equal to 2% of the calibration gas value. <br /> Instrument Serial No. �"/S/ <br /> Calibration Gas: %CH4 ( %CO2 %02 ,e <br /> i <br /> me CH4 CO2 02 <br /> )7 <br /> 2 SO rs /L <br /> Post-monitoring Calibration Check <br /> Time CH4 CO2 02 <br /> Stiff � � <br /> NOTES: <br /> Calibration Form GEM <br /> 3/31/06 11:54 AM <br />
