PASSIVE TYPE EMISSION FLUX SAMPLER

摘要

A passive type emission flux sampler measures an emission flux of a specified chemical sample released from an inspection object. The passive type emission flux sampler includes a hollow casing sealed except for an opening formed at a bottom for taking in a chemical substance. A test specimen that changes color in a reaction with the chemical substance is disposed to an inner surface of the casing opposite the opening. A water retaining material for maintaining the test specimen in a humid condition is disposed in the hollow casing.
