The LogTag® TICT iS0°Tag® is a tamper-proof electronic indicator which shows if the temperature has been at or below freezing point (0°C or 32°F) for 60 minutes or more.
While the temperature remains above freezing point, the display shows a tick symbol. If the temperature drops below freezing point for 60 minutes or more, the display shows a cross symbol, which cannot be reset or deleted.
The TICT 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.
Statistical data can be downloaded using a dedicated LogTag® Interface Cradle and freely available LogTag® Analyzer software.
TICT iS0°Tag® FREEZE TEMPERATURE INDICATOR
Product Model TICT iS0°Tag®. Sensor Measurement Range -25°C to +60°C (-13°F to +140°F). Operating Temperature Range -25°C to +60°C (-13°F to +140°F). Storage Temperature Range 0°C to +60°C (32°F to +140°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.
Actual performance is typically much better than the rated values. Please see the Rated Absolute Accuracy chart below.
Accuracy figures can be improved by recalibration.
Rated Temperature Reading Resolution 0.1°C for -25°C to +60°C.
LogTag Analyzer® currently displays to one decimal place of °C or °F. The native resolution is what is stored in the LogTag®.
