<p>[Problem] To accurately measure the corrosive gas in the atmosphere with an environmental measuring device and an environmental measuring method. [Solution] An environmental measuring device (10) comprising a computation unit (14) to calculate a first variation (Deltaf1m) for a first resonance frequency (f1m) of a first QCM sensor (11a) and a second variation (Deltaf2m) for a second resonance frequency (f2m) of a second QCM sensor (11b), the computation unit (14) correcting the second variation (Deltaf2m) on the basis of the first variation (Deltaf1m) within a first period (T1) and the second variation (Deltaf2m) within the first period (T1).</p> |
