The T802 Paramagnetic Oxygen Analyzer utilizes a technology that is non-
depleting and requires very little maintenance. However, there are a minimal
number of simple procedures that when performed regularly will ensure that the
analyzer continues to operate accurately and reliably over its lifetime. Repairs
and troubleshooting are covered in Section 11 of this manual.
Table 10-1 shows a typical maintenance schedule for the analyzer. Please note
that in certain environments (i.e. dusty, very high ambient pollutant levels) some
maintenance procedures may need to be performed more often than shown.
