Hello.
I have seen two or three Argweld purge monitors MKIII which would not want get calibrated - they show values from some minus 5 to plus 5 but never 20.9 (the usual oxygen %). Evidently, faulty sensors, but what made them out of order? Hot gas got on them? (They were used during welding of stainless pipes).
