The LogTag® TICT iS0°Tag® is a tamper-proof electronic indicator which shows if the temperature has been at or below freezing point (0°C or 32°F) for 60 minutes or more.

While the temperature remains above freezing point, the display shows a tick symbol. If the temperature drops below freezing point for 60 minutes or more, the display shows a cross symbol, which cannot be reset or deleted.

The TICT iS0°Tag® can be used to monitor the temperature of any freeze-sensitive product such as vaccine, food, or specialty chemicals for up to 3 years.

Statistical data can be downloaded using a dedicated LogTag® Interface Cradle and freely available LogTag® Analyzer software.

  • ‘Tick/Cross’ temperature indication with optional download via the TIC20/TICT Interface Cradle for a full breakdown of data.
  • Optional secondary upper alarm to monitor high temperature exposure.
  • Daily ‘Inspection Marks’ can be placed in statistics for quality assurance.
  • Complies with industry standards including EN12830. WHO PQS Prequalified under E006 devices : PQS Code E006/038
