EDGE® M-300 is a Bluetooth®-enabled reusable mobile sensor with the flexibility to monitor temperature-sensitive products during shipment or when in storage.

With a compact design and IP67 protection for variable environments, the EDGE M-300 is an advanced temperature sensor and data logger that can be used for a variety of cold chain applications.

A magnetic backing makes it easy to place inside containers and other metal enclosures for shipping while traditional screw holes allow it to be mounted to the wall of facility equipment.

The Bluetooth® wireless connectivity means data can be read through containers and coolers, as well as trucks, refrigerators and freezers to maintain the environmental integrity of the product throughout transit or storage. Three LED status lights provide visual confirmation of connection and notification of alarms.


With the free EDGEVue Mobile App, users can monitor EDGE M-300 temperature readings and geolocation data, as well as share data on-demand to the EDGECloud® right from their smartphones and tablets.

EDGEVue also gives you a fast and easy way to customise preferences, including setting alarms, data logging intervals, startup options and time and temperature units. There is no need for any other equipment or software installation.
