Abstract
Disclosed is a differential pressure volume flow air sampler that measures temperature in a collection cavity, differential pressure between the measured ambient pressure and air pressure in a collection cavity. These parameters are used to calculate the volume air flow across a collection disk using a processor which adjusts a blower to maintain a substantially constant volume air flow through said air sampler from the surrounding atmosphere.
