EDGE M-300 Mobile Temperature Sensors

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

Advanced Temperature Monitoring

With a compact design and IP67 protection for variable environments, the EDGE M-300 is an advanced  temperature sensor and datalogger 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.

EDGE Wireless Temperature Sensor Color ID RingsThe 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. EDGE M-300 is available with interchangeable colored sensor rings for quick identification of each individual sensor.

EDGEVue™ Mobile App for Anytime, Anywhere Access

With the free EDGEVue™ Mobile App, users can monitor 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 customize preferences. This includes setting alarms, datalogging intervals, startup options and time and temperature units. There is no need for any other equipment or software installation.
