Redoxitech is an R&D project conceived as research aimed at identifying, developing and validating non-invasive technologies applicable to supply and distribution networks for homonuclear diatomic gases (O₂, H₂, N₂, etc.). These technologies must be capable of characterising the entire network (gas behaviour, measuring instruments, etc.), enabling the early detection of leaks or the identification of errors in the measurement and control instrumentation located throughout the transport and distribution pipeline.
