Page 5: General Description
The SEM5000 is a digital gas detection instrument from QED Environmental Systems, Inc. The intended use of the SEM5000 is the measurement of low concentrations of methane in the field (Landfill surface emissions monitoring, leakage surveys of natural gas networks, control pinpointing outside buildings, quantifying methane fluxes, and laboratory applications for gas analysis). -

Page 13: Field Calibration
NOTE: The regulator flow must be a minimum of 0.6L/min to avoid restricting the pump. The SEM5000 package is provided with one demand-flow regulator with a C10 fitting. It is recommended that two regulators be used, (one per bottle), for ease of calibration. -
Page 14: Air Test 1
Connect the tubing from the gas regulator for the zero air calibration gas to the sample inlet of the SEM5000 NOTE: If the tube is not fully inserted into the sample inlet of the SEM5000, the concentration readings during field calibration may appear to be erratic and difficult to stabilize. -
