The Phoenix Mobilis is supplied with a list of calibration factors for common
gases (refer to
Table: Smallest detectable leak level
). It comes with 5
generic 'gas groups' with a variation in sensitivities which can be used as a
substitute for gases not listed in
Table: Smallest detectable leak level
(group 5 being the highest sensitivity through to group 1 being a low
sensitivity). Contact us for advice on which groups to use.
