Sample Ports
The Envision® gas analyzer has four (4) ports located on the front of the unit.
From the right to the left:
Calibrate/Static/Sample port – This port is used to calibrate the unit with calibration gas, to measure static wellhead
pressure, and to sample for gas quality.
Impact Port – This port is used to generate a differential pressure for calculating flow. Do not connect pressurized
calibration gasses to this port.
Available – This port is used to acquire an available (system) vacuum at the monitoring port. Do not connect pressurized
calibration gasses to this port.
Exhaust – This port is used to exhaust the gasses that are pumped through the sample train for measurement. Only connect
an exhaust hose to this port. Do not apply pressure to the exhaust port.
3 Safety
Landfill gas is normally safely extracted from landfills and conveyed to appropriate control devices. However, during the
course of monitoring each extraction point, exposure may occur. As such, it is important to follow all site-specific safety
protocols when monitoring. Typically a work at a landfill requires site specific health and safety plans. While performing
monitoring at a landfill, the user should be aware of the items included in that site specific health and safety plan. While the
Envision® gas analyzer is not for use in explosive atmospheres, it is important to know that all personal protection equipment
