Spare Analyzer Fuses
AMETEK recommends having on-site spare fuses used in the analyzer. These
fuses do not need to be changed out at regular intervals, but are necessary in
the event that a fuse has blown and a replacement is required.
When ordering replacement fuses, note the dierent ratings and Part Numbers
for the ATEX and CSA Certied Units for the Solenoid fuse; all other fuses are
the same for both units. Recommended fuses include:
