Sampling line maintenance (Permapure)
•
Do not bend, squash or deform the sampling line. Any “kink” in the sample line will reduce the internal lumen of the line and affect accuracy
of measurement.
•
Do not keep the sampling line open to the atmosphere, particularly in crowded or smoky environments. Keep the sampling line in sealed
plastic bag in a dark cool and dry place.
•
If saliva enters the tube it should be replaced immediately.
•
Periodically grease the O-ring on the connector to ease fitting to optical flowmeter.
•
Replace the sampling line every 100 exercise tests or 200 PFT test or every 6 months. In any case, sampling line will become discoloured
(brown) with age and may cause calibration to fail.
Note : ALWAYS replace sample line as the first step in troubleshooting a failed gas calibration.
