The probe system as claimed in claim 1, wherein: said treatment chamber part is formed of a material, that is chemically inert. 3. The probe system as claimed in claim 2, wherein: the synthetic material comprises PVDF (polyvinylidene fluoride), PEEK, PFA (perfluoroalkoxy alkane), PTFE (polytetrafluoroethylene). 4. The probe system as claimed in claim 1, wherein: all components of the probe system, which in a position of said immersion tube, come in contact with the process medium, are formed of a chemically inert material. 5. The probe system as claimed in claim 1, wherein: said treatment chamber part, by means of said support structure, is secured to said connector apparatus in a shape-interlocking manner. 6. The probe system as claimed in claim 1, wherein: said connector apparatus includes a flange connected with said support structure, which is connectable, with interpositioning of an annular gasket, to a complementary flange of said process container. 7. The probe system as claimed in claim 6, wherein: a connector apparatus-end of said treatment chamber part has an annular shoulder, which sits in a seat formed by an axially extending port of said annular gasket; anda gap formed between said seat and said treatment chamber part is sealed from the process container by means of at least one ring seal. 8. The probe system as claimed in claim 7, wherein: said seat formed in said port of said axially extending gasket has an annular groove, in which is accommodated a wiping ring bearing against said immersion tube. 9. The probe system as claimed in claim 6, wherein: said gasket is composed of the same material as said treatment chamber part. 10. The probe system as claimed in claim 1, wherein: said treatment chamber part has on its connector apparatus-end a plug-like projection, which is embodied so as to enter into a complementary port of said process container; andsaid connector apparatus includes a holding ring, which is securable to said complementary port by means of a coupling nut, and which has an annular area facing away from the process container, on which bears an annular step formed in the outer wall of said treatment chamber part. 11. A probe system for measuring a measured variable of a process medium contained in a process container, comprising: a connector apparatus connectable with connecting means of the process container;a treatment chamber part forming a treatment chamber and having at least one treatment medium supply line communicating with said treatment chamber,a measuring probe with measuring head embodied for registering measured values, wherein said measuring probe is accommodated in an immersion tube seated so as to be axially shiftable between a measuring position, in which said measuring head is arranged outside said treatment chamber, and a treatment position, in which said measuring head is retracted into said treatment chamber, said immersion tube, on its connector apparatus-side front end, has a front-end closed, protective cylinder, and said measuring head is arranged in a perforated section of said immersion tube behind said protective cylinder, so that, in the measuring position of said immersion tube, said measuring head is contactable via perforations with the process medium, and in the treatment position of said immersion tube, is contactable with the treatment medium; anda drive system for axial shifting of the immersion tube, arranged on the end region of the probe system facing away from said connector apparatus;wherein said treatment chamber part is surrounded by a support structure connected with said connector apparatus and with said drive system; andsaid treatment chamber part, by means of said support structure, is secured to said connector apparatus in a shape-interlocking manner. 12. The probe system as claimed in claim 11, wherein: said treatment chamber part is formed of a material that is chemically inert. 13. The probe system as claimed in claim 12, wherein: the synthetic material comprises PVDF (polyvinylidene fluride), PEEK, PFA (perfluroalkoxy alkane), PTFE (polytetrafluoroethylene). 14.
