LogTag TIC20

Tamper-proof WHO temperature indicator

Tamper-proof WHO temperature indicator


  • Factory pre-configured to monitor a range of standard vaccines - 4 WHO PQS Pre-qualified models available
  • At-a-glance summary with ‘OK’/’Reject’ alarm status.
  • Review statistical data on device for up to 40 days prior.
  • Robust and Accurate. Data collected is secure and cannot be manipulated

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.

Product Model TIC20
Temperature Sensor Measurement range -30 °C to +60 °C (-22 °F to +140 °F)
Recorder operating temperature range -30 °C to +60 °C (-22 °F to +140 °F)
Storage Temperature Range -30 °C to +65 °C (-22 °F to +149 °F).
Rated Temperature reading accuracy Better than ±0.5 °C for -10 °C to +40 °C (+14 °F to +104 °F). Better than ±1.0°C for -30°C to -10°C (-22°F to +140°F). Better than ±1.0°C for +40°C to +60°C (+104°F to +140°F).. Actual performance is typically much better than the rated values.

Ready-Mode Push any button. “Ready” shows the indicator is ready to be started.

Start Mode Press and hold the Start button. “Monitoring” will flash. Release Start button when flashing stops. The Indicator is now in the 60 minute start delay.

Monitoring Mode “Monitoring” appears on the display. The indicator is now taking a temperature reading every 6 minutes. Elapsed time in hours and days appears on the display. If an Alarm occurs, the day segment is illuminated and the OK symbol is replaced by an X.

Review Mode Press the Review button to view statistics for each day.

Stopped Mode Press and Hold the Stop button. “Stopped” will flash. Release Stop button when flashing stops. The Indicator is now Stopped.
