TICT Temperature indicator

Applications

The LogTag TICT is a low cost disposable electronic temperature indicator for use in monitoring temperature & time statistics in transport applications of up to 45 days duration.

Product Summary

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.

Features:

Factory pre-configured to monitor a range of products including standard vaccines.
Standard 60 minute start delay
Clear indication of alarm status at all times.
Monitors for up to 45 days
Push button Start and Stop.
Data can be downloaded via an interface cradle and LogTag Analyzer if required.
Robust and Accurate. Data collected is secure and cannot be manipulated.
Fits easily into packages and can be mailed via letter rate.

Modes of Operation:

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.
