Re: Mobrey gas tester
Very interesting. Probably used to check domestic heating boilers and probably works by infra-red spectroscopy (infra red gas analyser =IRGA). Instruments like it go back for a very long time, even had valves in them! I pulled a few apart. In the days before hi-tech stuff was helium leak-checked with mass spectrometers, they used IRGA's with nitrous oxide.
