The EL-SMS-2G-VAC is a battery powered temperature alert that will send SMS (Short Message Service) notification messages to pre-programmed mobile phone numbers whenever the temperature it is monitoring exceeds an upper or lower temperature limit. The unit is supplied with a thermistor inserted into a glycol bottle, designed to accurately mimic the internal temperature of a vaccine rather than the ambient temperature of the fridge in which the vaccines are stored and a traceable calibration certificate.

Configured using the EasyLog SMS App on Google Play and the App Store, the EL-SMS-2G-VAC can also send periodic summary messages to confirm that it is running normally including the minimum, maximum and average temperature since the previous summary message. The unit must be fitted with a microSIM card purchased separately to allow it to register onto a 2G GSM network. This product meets and exceeds CDC standards for vaccine monitoring.


The EL-SMS-2G-VAC is suitable for a wide variety of applications. These include:

  • Vaccine Storage
  • Cold Chain in the Pharma Industry
  • Blood & Blood Component Storage
