Question 1

How do we know the logger was not moved or tampered with inside the container during the voyage?

Accepted Answer

Each logger is secured with a tamper-evident adhesive mount and a numbered security seal, and the audit log records any attempt to connect to the device mid-voyage. The final report flags any mid-voyage data access events so the receiving quality team can assess whether the chain of custody remained intact.

Question 2

Can one logger cover an entire reefer container or do we need multiple units?

Accepted Answer

For regulatory documentation purposes, a single logger placed at the warmest point of the container satisfies GDP requirements for a worst-case temperature record. For larger containers or shipments requiring spatial mapping, multiple loggers can be deployed and their data merged into a single multi-point voyage report.

Question 3

What logging interval is recommended for a 30-day voyage to balance battery life and data resolution?

Accepted Answer

A 15-minute interval provides more than sufficient resolution to identify excursion events and their duration while keeping battery consumption well within the 90-day rated capacity. For voyages where port dwell time at hot intermediate ports is the main risk, a 10-minute interval during the first and last 48 hours can be pre-configured to capture higher-risk handling windows.
