TICT iS0°Tag® FREEZE INDICATOR

Applications

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

Product Summary

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

The 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. If a freezing event occurs the symbol is displayed and the indicator is locked. Once locked, the indicator cannot be re-used.

The iS0°Tag® is factory configured with a low temperature limit of -0.5 °C for a duration of 60 minutes. The iS0°Tag® can also be factory configured for a different low temperature limit down to -5.0 °C for monitoring items with lower freezing points. An optional upper Alarm limit is also available.

Features:

Factory pre-configured to monitor a range of products including standard vaccines.
Clear indication of alarm status at all times.
Monitors temperature and records daily statistics for up to 3 years
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.
Up to three days of logged real time temperature readings either side of alarm activation

Modes of Operation:

Starting the Indicator Press and hold the START/MARK button. "RUN" will flash. Release button when flashing stops. The Indicator enters factory preset delay or begins taking readings.

Monitoring When "RUN" appears on the display, the indicator is taking a temperature reading at the pre-configured interval (typically every 5 minutes). If an Alarm oc- curs, the symbol is replaced by an symbol and the cor- responding alarm arrow is also displayed.

Stopping Press and hold the START/ MARK button. First the arrows will flash, then "RUN". Release button when flashing stops. Indicator also stops when bat- tery is empty or an alarm occurs.
