Hallo, I need some MTBF's. I need it for a reverse osmosis and a demineralizer cartridge for a residential system. And I need the MTBF for a conductivity measurement in water. Have anybody an idea for a fuel cell ( PEM ), or for membranes? Thanks for helping! Best regards from Germany. David Wegener

Use the NPRD-95 as a baseline for MTBF Numbers.
