Electronic Indicator LogTag® TICT iS0°Tag®
The LogTag TICT iS0°Tag® is a tamper-evident, irreversible electronic indicator. As long as the measured temperature remains above freezing, the display shows a symbol. If the temperature falls below freezing (0°C) for 60 minutes or longer, the display shows a symbol that cannot be reset or cleared.
The iS0°Tag® can be used to monitor the temperature of freeze-sensitive products such as vaccines, food, or specialty chemicals for up to 3 years. Once a freeze alarm occurs, the symbol is displayed, and the indicator is then excluded from further use. Once the alarm is triggered, the indicator cannot be reused.
The iS0°Tag® is factory-set with a lower temperature limit of -0.5°C for a duration of 60 minutes. The iS0°Tag® can also be configured for other lower temperature limits (up to -5.0°C) to monitor products with different freezing points. An upper temperature limit is also optional.
