Corrosive environment monitoring apparatus and method

A corrosive environment monitoring apparatus comprising one or more vent ducts in which specimens are installed, the corrosive environment monitoring apparatus adapted to measure the corrosiveness in an ambient environment from the corroded condition of the specimens,

• wherein the each specimen has a region subject to the measurement, the region being made of the same metallic material, and
• wherein the longitudinal direction of each of the regions subject to the specimen measurement formed in the vent ducts is in parallel with or along the direction in which a corrosive substance in the ambient environment passing through the vent ducts flows.

A corrosive environment monitoring method in which at least one vent duct having a specimen installed thereon is provided and the corrosiveness in an ambient environment is measured from the corroded condition of the specimen,

• wherein monitoring is performed by installing the specimen having a region subject to the measurement formed in one vent duct or a plurality of vent ducts arranged in parallel with one another, the region being made of the same metallic material.
