Hi Kev,
I have an old Kane 455 analyser that I may be thinking of getting serviced/recalibrated. It must be circa 11-12 years old but still works fine for pressure, temp etc. It reads CO but not CO2.
If I recall correctly it used to be the case that only Kane could replace the O2 cells on these, Is that still the case? Or is this something you guys at GES would be able to do?
