Designed as a Single-use, cost effective & reliable temperature recorder, the LogTag® USRIC-4 measures and stores real time temperature readings over a measurement range of -30°C to +60°C (-22°F to +140°F). The USRIC-4 combines all the features of an advanced temperature recorder with a 3937 log memory and a 6-month operating life in a robust and inexpensive package.
The USRIC-4 plugs directly into the computer USB for easy configuration by the user for a wide range of recording and alert conditions. Readings are downloaded using LogTag Analyzer®, which provides facilities for displaying data in chart, table or statistical formats and allows electronic archiving, export or transmission of the data in support of sophisticated data management systems.
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.
Accuracy figures can be improved by recalibration.
|Rated Temperature Reading Resolution||Less than 0.1°C/F.|
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||3937 temperature readings. 14 days @ 5min logging, 41 days @ 15min logging.|
|Sampling Interval||Configurable from 1 minute to 18 hours.|
|Logging Start Options||Push button start or specific date & time.|
|Alarms||1 configurable upper and 1 configurable lower alarms.|
|Recording Indication||Flashing ‘OK’ indicator / flashing ‘ALERT’ indicator.|
|Download Time||Typically less than 4 seconds for full memory (3937 readings), depending on computer or readout device used.|
|Environmental||IP64 with USB cap fitted.|
|Power Source||CR2032 3V LiMnO2 Battery (Fixed).|
|Battery Life||2 years storage, followed by 6 months normal use.|
|Real Time Clock||Built-in real time clock.|
Rated accuracy ±25ppm @ 25°C (equivalent to 2.5 seconds/day).
Rated temperature coefficient is -0.034 ±0.006ppm/°C (I.e typically +/- 0.00294 seconds/day/°C).
|Connection Interface||USB 2.0, A-type plug|
|Software||LogTag® Analyzer 2.5 or higher, PDF Generator|
|Size||93mm(H) x 54.5mm(W) x 8.6mm(T).|
|Footnote||*(-30°C to +60 °C applies to Loggers with serial numbers 5x34x33580 or greater. Loggers with serial numbers prior to this have an operating temperature range of -25°C to +60°C).|
