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.
| Product Model |
TICT iS0°Tag |
| 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 +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. 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® |
| Sensor Reaction Time |
Typically less than 7 minutes (T90) in moving air (1m/s) |
| Recording Capacity |
Minimum & Maximum temperature for each of the 1096 days. Duration of excursion beyond alarm limits for each day. Up to 270 recorded real time temperature values each before and after the alarm has triggered. |
| 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). |

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.
