Continuous Monitoring
Continuous monitoring systems for temperature and humidity provide a record of the conditions inside a shipping container during its journey. Transit environmental logging uses small electronic sensors placed among the fabric rolls to capture data at regular intervals. This information is used to assess whether the textiles were exposed to conditions that could cause mold, mildew or permanent color changes.
Data Capture
Sensors record the peaks and valleys of humidity as the ship moves through different climate zones. If the transit environmental logging shows that the relative humidity exceeded ninety percent for several days, the buyer can prepare for a detailed inspection upon arrival. The data reveals exactly when a moisture excursion occurred, such as during a heavy rainstorm at the loading dock.
Dispute Resolution
Insurance claims for water damage rely on the timestamped evidence provided by these logs. Without transit environmental logging, it is difficult to prove whether the damage happened at the factory, on the sea or in the final warehouse. The record helps in assigning liability to the correct party in the supply chain.
This transparency reduces the number of legal conflicts between mills and buyers.
Hardware Requirement
Devices must be rugged enough to survive the vibrations and temperature extremes of ocean transport. Battery life is a critical specification, as the logging must continue for the entire duration of the voyage, which can last several weeks. The data is typically downloaded via a wireless connection once the container is opened at the destination.
