LogTag® TIC20 Tamper-proof WHO temperature indicator

LogTag® TIC20 Tamper-proof WHO temperature indicator


The LogTag TIC20 is a disposable electronic temperature indicator for use in monitoring temperature & time statistics in pharmaceutical transport applications of up to 20 days duration.

Product Summary

Current temperature, elapsed time, load status, monitoring status and battery condition can all be seen at a glance at any time during the trip. On arrival at the destination, monitoring can be stopped and the user can then review time and temperature statistics for each day of the trip, up to 20 days maximum.

The LogTag TIC20 is factory pre-configured for one of a range of monitoring profiles. Special profiles are available on request, subject to conditions.

Statistical data can be downloaded from the TIC20 using an interface cradle and freely available LogTag Analyzer operating software if required.

The TIC20 offers an accurate and cost effective solution for monitoring the pharmaceutical cold chain in “last mile” distribution and other applications where full data logging capability is not required.
