The invention discloses a typical environment monitoring method for low-pressure metering boxes. The typical environment monitoring method comprises on-site operation detection and outdoor stewing detection; during the test, various low-pressure metering boxes are selected; during the on-site operation detection, environmental data, environmental data in box bodies and appearance and temperature rise data of the box bodies are monitored, so that a multi-index influence rule and an index change tendency under an extreme environmental condition are obtained; during the outdoor stewing detection, the low-pressure metering boxes are exposed in a typical environment for a period of time to perform material testing on the low-pressure metering boxes before and after the exposure, and corrosion conditions of metal parts in the low-pressure metering boxes are verified, so that performance change estimation is performed on materials of the low-pressure metering boxes. The typical environment monitoring method for the
