Electronic temperature indicator

Electronic temperature indicator


  • Factory pre-configured to monitor a range of products including standard vaccines - 2 upper and 2 lower temperature alarms
  • ‘Tick’/’Cross’ display shows temperature alarm status
  • Collect daily minimum/maximum temperature statistics for up to 45 days
  • Download of statistical data via optional interface
  • Robust and Accurate. Data collected is secure and cannot be manipulated
  • Fits easily into packages and can be mailed via letter rate


The LogTag TICT can monitor and record statistics against four factory pre-set temperature limits for up to 45 days, displaying a tick mark if environmental conditions remain within limits. If temperatures exceed two high temperature alarm limits or go below two low temperature alarm limits, the LCD shows a REJECT alert, indicating the goods require further checking.

The LogTag TICT 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 TICT using the LogTag Indicator interface cradle and freely available LogTag Analyzer operating software if required.

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

Product Model TICT
Temperature Sensor Measurement range -25 °C to +60 °C (-13 °F to +140 °F)
Recorder operating temperature range -25 °C to +60 °C (-13 °F to +140 °F)
Storage Temperature Range 0 °C to +40 °C (32 °F to +104 °F).
Rated Temperature reading accuracy Better than ±0.5 °C for -10 °C to +25 °C. Better than ±1.0 °C for -25 °C to -10 °C Better than ±1.0 °C for +25 °C to +60 °C
Rated Temperature Reading Resolution 0.1 °C for -20 °C to +60 °C
Sensor Reaction Time Typically less than 7 minutes (T90) in moving air (1m/s)
Recording Capacity Minimum & maximum temperature for each of the 45 days. 1st activation of each alarm for each day including trigger time and duration of each event. Please note the TICT does not store each individual temperature reading taken
Alarms Four factory pre-set alarm events, two over temperature and two under temperature. Each alarm event can be instant reject or accumulative reject. It can also be disabled.
Environmental IP64
Power source CR2032 3V LiMnO2 Battery (Fixed)

Weight 23 g
Sampling Interval Factory pre-set between 1 and 59 minutes; 5 minute interval for profile 0001
Logging Start Options Push button start. Factory pre-set between 1 and 255 minutes; 60 minute delay for profile 0001
Recording Indication OK  = Temperature has remained within the alarm limits. Reject X = Alarm event has been generated
Case Material Polycarbonate

Ready Mode Push the START/STOP button. “Ready” shows that the indicator is ready to be started.

Start delay mode Press and hold the START/STOP button. “RUN” will flash. Release button when flashing stops. The Indicator now begins the preset start delay.

Run Mode “RUN” appears on the display. The indicator is now taking a temperature reading at the factory stipulated interval (typically every 5 minutes). If an Alarm occurs the symbol is replaced by an X symbol and the corresponding alarm limit code (HT1, HT2, LT1 or LT2) is also displayed.

Stopped Mode Press and Hold the START/STOP button. “Stopped” will flash. Release button when flashing stops. The Indicator now no longer takes readings.

Factory Configurations LogTag TICT can be factory configured to support a large range of different monitoring and alarm configurations (see specifications over page for details).
