Replacing the Sample Tubing
The SEM5000 exdentable sample probe contains a 5-foot section of tubing that directs the
sample into the instrument. Should the tube become kinked or break, it must be replaced to
avoid restricting the pump or causing errors in the concentration readings.
To replace the tubing:
Unscrew and remove the windscreen from the end of
the sample probe
Remove the cellulose dust filter from the end of the
filter holder
Unscrew and remove the nut at the top of the filter
holder and remove the filter holder from the end of the
sample probe
Using a 3mm allen wrench, release the nut inside the
filter holder
