Eclipse Purity and Flow Rate Test Procedure - Preferred Method
It is recommended that the Eclipse be tested for oxygen concentration and flow performance. SeQual
recommended test setup is shown on the following diagram. Oxygen monitors may or may not have an
internal pump to draw samples of oxygen to be measured. Placement of the oxygen monitor in the test
setup depends whether they have an internal pump. Only one oxygen monitor is needed though. An
oxygen monitor such as Salter Labs’ PRO
2
Check Elite™ or equivalent may be used.
• Connect the circuit per the diagram shown below.
• Turn the concentrator on and set the target flow on the Eclipse to 3 LPM continuous flow.
• Allow the Eclipse to stabilize (can take up to 10 minutes).
• Verify the O
2
concentration and O
2
flow rate are within specification.

NOTE:
The Eclipse oxygen concentration and flow sensor cannot be calibrated
in the field. If you suspect that the Eclipse flow and oxygen purity
measurement is out of calibration, please return it to SeQual for
service.
Purity and Flow Rate Test Procedure-Alternate Method
Attach a calibrated oxygen monitor to the oxygen outlet port in accordance with oxygen monitor
manufacturer’s recommendations.
NOTE:
Some sensing equipment may restrict the actual flow rate below what
the Eclipse can provide and provide inaccurate concentration readings.
If testing is performed with the oxygen monitor in the alternate location
pictured above, ensure that the oxygen monitor does not significantly
restrict oxygen flow.
