USRIC-4
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.
Specifications
Features
| Product Model | USRIC-4. |
| 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 | 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 |
