Notification by SMS and email
Thanks to a programmable built-in cellular module, it enables operators all around the world to receive automatically generated real-time alerting or warning messages by SMS and/or email. Additionally, it can be easily integrated into a web-based server application.

SMS warnings prevent damage of the goods
In case of a temperature deviation, the Fridge-tag 3 immediately sends a notification by SMS to the predefined person(s) in charge. A fully comprehensive emergency plan can now be activated in order to prevent damage of the goods.

Alarms and 30-day history visible on the display
As long as the temperature is within the permitted range, the OK sign is shown on the display. If the indicator is exposed to an out-of-range temperature the ALARM sign appears on the display. The device shows the actual temperature in degrees Celsius or Fahrenheit, all alarm violations over the previous 30 days (on a rolling basis), the daily minimum and maximum temperature of the last 30 days and the time duration of any violation.
