QUÉBEC, CANADA, MARCH 31, 2021 MULTIWAVE FIBER OPTICS MODELS PFO3372, PFO3371 END OF LIFE NOTICE ABB QUEBEC FACTORY – MW PRODUCT LINE PFO3372 – END OF LIFE The demand for the Fiber Optic Multiwave (PFO3372) has been minimal over the last fifteen years with no demand in the last three years. For this reason, effective immediately, the analyzer will be placed in the LIMITED phase for the next 10 years and no more units will be manufactured. Standard spare parts and routine maintenance of the analyzer remain available, as PFO3372 uses parts of the ACTIVE analyzers PUV3402 and PIR3502. However, spare parts and services on the fiber optics module will be on a best-effort basis. Customers looking to replace an old PFO3372 analyzer can contact ABB factory sales support (qc_rfq@ca.abb.com). An application specialist will evaluate the feasibility to offer an alternative solution. Most PFO applications can be supported by the following products: PUV3402 (working in the UV without fiber optics) PIR3502 (working in the IR without fiber optics) TALYS ASP500 (working in the NIR with fiber optics) In the event that an alternative analyzer is not suitable for a spefic application, there is potential for a custom solution. PFO3371 – END OF SERVICE The PFO3372 model replaced the former PFO3371 model. PFO3371 production was stopped before 2006 and has been under the OBSOLETE phase since 2016. Please note that electronics of this analyzer are no longer supported and other spare parts availability is very limited. ABB will cease all service support on PFO3371 units on December 31, 2022. Customers using a PFO3372 or a PFO3371 are invited to discuss a transition plan with ABB local sales representatives or channel partners, to be supported by ABB factory sales support (qc_rfq@ca.abb.com).
