1. A corrosive environment monitoring device comprising:
a steam extraction part that extracts steam from inside of a casing of a steam turbine to outside thereof;
a condensed water storage part that stores therein condensed water produced by condensation of steam passing through the steam extraction part; and
a corrosion factor sensor part that detects properties of the condensed water, wherein
the condensed water storage part includes a gap simulation part that simulates a gap inside the turbine and has a predetermined gap capable of storing the condensed water therein, and an annular channel formed on an outer periphery side of the gap simulation part, and
the corrosion factor sensor part includes one or more sensors capable of measuring the properties of the condensed water, and a switching part configured to be capable of switching between contact and non-contact between the one or more sensors and the condensed water stored in the gap simulation part.
