2.4.3
Replacement of Nafion ® sampling line and filter
In order to improve life of the Oxygen sensor the gas sample taken
during testing is dried. This is done using a sample filter and Nafion ®
drying line, integrated into the gas sample tube. Both the filter and
the Nafion ® tube should be replaced at regular intervals. A new
sample tube is transparent but with use this tube will turn yellow and
then brown in colour this change will reduce the effectiveness of the
tube to dry the sample and it should be exchanged.
Geratherm Respiratory recommends that the in line filter is
exchanged with the Nafion (R) tube.
Both items may only be purchased from a local Geratherm
Respiratory service partner.
Saliva or high humidity within the tube can affect the
measuring accuracy of the Ergostik. The tube and filter should
be replaced in this case.
