Generator H2 purity meter

Hi there everyone,

I'm looking for anyone who has experience in replacing the analogue H2 purity meter in GE machines. I'm using Frame 9E gas turbines and SC3 steam turbine. The existing purity meters are not accurate and are problematic. I was told that the meter is now obsolete. Are there any purity meters available in the market (OEM and non-OEM) that can be used as a direct replacement or with very less modification?

Yokogawa, GE Panametrics, E/One. All of these came up at the top of a Google search for "H2 purity analyzers". ABB, also.
