RGA Replacement Ionizer Kit
Ionizer Replacement kit for the RGA100, RGA200 and RGA300 (SRS Part# O100RI)
The Ionizer Replacement kit (SRS# O100RI) contains all the parts needed to completely replace the
ionizer of the SRS Residual Gas Analyzers models RGA100, RGA200 and RGA300. The
replacement parts are pre-cleaned at the factory and should only be handled by qualified personnel
following the most strict vacuum compatible procedures. Do not open the sealed plastic bags until
ready for the replacement procedure. The wire-mesh cages are very delicate and should be handled
with extreme care.
