The FlashLink RTL Prime In-Transit Logger monitors and reports temperature, location and light during transport of temperature sensitive products. It is ideal for local area deliveries and intercompany transfers. Tracking routes is easy with a user-friendly online dashboard to remotely access real-time information and conditions in a truck or container, even before a shipment reaches the dock.

This 2-in-1 logger provides reports that are downloadable from the web application, plus an on-board PDF file as a backup, so receivers have immediate access to trip data if there's no cellular service when a load arrives. Other beneficial features include 12-month battery shelf life and Flight Mode feature, which allows shippers to temporarily disable transmission during air shipments, in compliance with FAA guidelines. The light sensor detects door openings, which can indicate inspections and unloading upon arrival, or unexpected opening that could be due to tampering with cargo.

The inside of sleeve provides a peel-away barcoded trip label for attaching to shipping documents, and a place to write down shipping information, such as date/time and purchase order number.

The back of the sleeve has a self-adhesive strip for securely mounting the RTL logger onto a shipping carton. There are receiver instructions with a URL address so trip data can be retrieved from the secure web portal when a load arrives. A Merchandize Return Label is available for easy recycling through the United States Postal Service, when returning loggers within the USA.
