1. A multipoint air sampling system, the system comprising:
a field reference subsystem carrying out a recurrent verification of one or more sensors associated with the multipoint air sampling system;
a permeation source within the field reference subsystem which source is calibrated as a transfer standard, wherein the permeation source generates one or more test gasses used to evaluate an integrity of the one or more sensors;
a processor configured for executing a logic module for rating the integrity of the one or more sensors, wherein the processor executes the logic module in response to the recurrent verification of the one or more sensors; and
a report generator configured for generating a reporting action in response to the recurrent verification of the one or more sensors.
