Most safety supply houses carry both the detection units and the
ampoules (commonly called Drager tubes) though they will most likely
have to order the ampoules. If you can find a catalogue from one of
the larger companies, it should list the different tubes with their
corresponding measuring (concentration) range. It should be noted
that the tubes do have a specific shelf life so don't order more
than you need.
