Designed as a Single-use, cost effective & reliable temperature logger, the LogTag® USRIC-8 measures and stores real time temperature readings over a measurement range of -30°C to +60°C (-22°F to +140°F).
The USRIC-8 combines all the features of an advanced temperature logger with an 8,000 log memory with a shelf life of up to two years before configuration (in standard hibernation mode) and a 6-month operating life in a robust and inexpensive package.
The USRIC-8 plugs directly into the computer USB for easy configuration by the user for a wide range of recording and alert conditions. Upon download, it automatically generates a fully detailed PDF report with the option to download the data using the freely available LogTag® Analyzer software for a more detailed analysis.
A red ALERT indicator provides an immediate indication – without access to a PC – if any readings are outside the limits specified at the time the unit was configured. A green OK indicator provides immediate visual confirmation that the unit is operating.
|Sensor Measurement Range||-30°C to +60°C (-22°F to +140°F).|
|Operating Temperature Range||-30°C to +60°C (-22°F to +140°F).*|
|Storage Temperature Range||0°C to +40°C (32°F to +104°F).|
|Rated Temperature Reading Accuracy||Better than ±0.5°C (±0.9°F) for -5°C to +30°C (23°F to +86°F).
±0.8°C (±1.5°F) or better for measurements in other areas of rated range.
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||Less than 0.1°C/F.
Please see the Rated Native Resolution chart below.
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 5 minutes (T90) in moving air (1m/s).|
|Recording Capacity||8,001 temperature readings. 27 days @ 5min logging, 80 days @ 15min logging.|
|Sampling Interval||Configurable from 1 minute to 18 hours.|
|Logging Start Options||Push button start or specific date & time.|
|Recording Indication||Flashing ‘OK’ indicator / flashing ‘ALERT’ indicator.|
|Download Time||Typically with full memory (8,001 readings) in less than 20 seconds from time of insertion to availability of PDF report.
Typically less than 10 seconds from time of insertion to availability of LTD file in LogTag® Analyzer (if configured).
|Environmental||IEC 60529: IP64 with USB cap fitted.|
|Power Source||CR2032 3V LiMnO2 Battery (Fixed).|
