EDGE S-400® is a wireless, portable sensor for monitoring and controlling cold chain performance.

Key features of the EDGE S-400 are:

  • Bluetooth® enabled temperature sensor
  • Check temperature readings wirelessly from smartphone or tablet
  • Single or multi-use with three month battery life
  • Internal sensor and memory for 4,000 datapoints
  • Wireless access through packing materials, containers, cold equipment, and cold rooms
  • Cloud sharing and storage
  • Robust IP65 protection against dust and projected liquids

EDGE S-400 is an easy-to-use, practical, and cost-effec¬tive solution for wireless temperature tracking. Small enough to fit into almost any size and type of container, cooler, or enclosure, it can be used to monitor cold-chain performance for temperature-sensitive products without compromising the shipment packaging integ-rity. In addition, an adhesive backing makes placement simple and reliable.

Embedded sensors and Bluetooth® wireless connectivity provide temperature datalogging continuously through the product’s journey. Using the free EDGEVue® app, temperature readings and geolocation data can be easily accessed and shared on demand with iOS and Android smartphones and tablets.

EDGEVue provides easy user access to establish cus¬tomised parameters for each use of the EDGE S-400, including alarms, datalogging intervals, startup options, and time and temperature units. Data can be transmitted to Google Drive, Dropbox, or the EDGEVue Cloud, providing global data access.
